Direct Answer

INA §237(a)(2)(B)(i) excludes a single offense involving possession for personal use of 30 grams or less of marijuana. BIA precedent treats the exception as a circumstance specific inquiry into the conduct on a single occasion rather than a purely categorical comparison.

The Exception Is Written Into the Deportability Ground

The controlled substance ground excludes a single offense involving possession for one's own use of 30 grams or less of marijuana. This is not a general legalization rule and does not erase other immigration consequences of marijuana related conduct.

The defense must prove that the conduct fits the statutory description: a single offense, possession, personal use, marijuana, and a quantity of 30 grams or less.

Single Offense Does Not Always Mean One Count

Matter of Davey held that the phrase can cover more than one statutory crime when all offenses are closely related to one incident of personal possession of 30 grams or less and none is inherently more serious than simple possession.

The analysis therefore looks beyond the number of counts. At the same time, separate incidents or an offense inherently more serious than simple possession can place the case outside the exception.

The Conduct Must Involve Possession

The exception is directed at possession, not trafficking, distribution, manufacture, or other inherently more serious conduct. A conviction label should be compared with the actual statutory and factual basis permitted under the circumstance specific inquiry.

Counsel should identify whether any companion offense changes the essential nature of the event. The exception should not be stretched to cover conduct Congress treated differently.

Possession Must Be for the Respondent's Own Use

Personal use is an express part of the exception. Evidence of sale, delivery, packaging for distribution, or possession for another person can create a factual dispute even where the quantity was small.

The defense should gather the plea record, police quantity evidence, laboratory reports, and other reliable documents that address why the marijuana was possessed.

Quantity Is a Factual Question

Thirty grams is the statutory ceiling. When the conviction record does not establish the amount, the respondent may need credible testimony or other reliable evidence to show that the incident involved no more than the permitted quantity.

Do not infer quantity from the misdemeanor label. State criminal grading rules do not necessarily use the same 30 gram threshold as federal immigration law.

The Inquiry Is Circumstance Specific

Matter of Dominguez-Rodriguez reaffirmed that the exception calls for a circumstance specific inquiry into the respondent's conduct on a single occasion. The court is not confined to asking whether every violation of the criminal statute necessarily involves 30 grams or less.

That difference from the categorical approach makes evidentiary preparation important. The respondent should affirmatively document quantity, personal use, and the relationship among any companion counts.

The Party Seeking the Exception Should Build an Affirmative Record

Because the exception removes conduct from the controlled substance deportability ground, burden questions can depend on the procedural posture and proof already offered by DHS. In practice, a respondent who relies on the exception should be prepared to prove the facts that place the offense within it.

A sparse criminal record is not always fatal, but it makes corroborating evidence more important. Counsel should identify admissible, reliable sources rather than wait until the individual hearing.

Do Not Confuse the Exception With the Initial Drug Match

A respondent can have two distinct defenses: the conviction may fail to match a federally controlled substance under the categorical framework, or the conviction may match but fall within the 30 gram personal use exception.

Brief the theories separately. Dor and Felix-Figueroa address controlled substance matching questions, while Davey and Dominguez-Rodriguez govern the circumstance specific exception.

The Exception Is Not a Universal Drug Waiver

A sustained a marijuana possession charge charge does not answer every relief question. Counsel should separately review cancellation, adjustment, waivers, asylum related protection, withholding, Convention Against Torture protection, VAWA remedies, post conviction options, and any other relief supported by the respondent's status and history. Other statutes can use different marijuana exceptions or no exception at all.

The same incident should be screened separately for inadmissibility, naturalization good moral character, cancellation eligibility, and discretionary consequences.

The Exception Focuses on Conduct From a Single Occasion

Davey permits closely related counts arising from one possession incident, but separate criminal episodes should not be collapsed merely because they were resolved in the same plea or court case.

Build a timeline of possession events, dates, locations, and counts so the Immigration Judge can see whether the conduct truly involved one occasion.

Quantity Evidence Can Come From Several Reliable Sources

When the judgment does not specify weight, laboratory reports, plea stipulations, charging documents, property records, and credible testimony may help establish the amount. The reliability and procedural use of each source should be explained.

A package count or street value should not be converted into grams without a supported evidentiary basis.

Personal Use Is a Separate Factual Requirement

Small quantity alone does not prove personal use. Packaging, scales, sales messages, admissions, cash, and the plea theory can support or undermine the personal use claim.

Conversely, the government should not infer distribution simply from possession of multiple containers if the record does not establish an intent to sell.

Do Not Import Other 30 Gram Provisions Without Checking Their Text

Immigration law uses 30 gram marijuana language in several contexts, including waivers and special adjustment provisions. The wording and burden are not identical in every statute.

Citations from an inadmissibility or adjustment case can be useful by analogy, but the brief should explain why the reasoning applies to §237(a)(2)(B)(i).

Where DHS Usually Attacks the Marijuana Exception

DHS generally does not need to dispute that the conviction involved marijuana. The contested point is usually whether the conduct fits every limit in the statutory exception: one offense, possession, personal use, and 30 grams or less. Companion counts, admissions about sharing or sales, and evidence of aggregate quantity can become central because the BIA treats the exception as a circumstance specific inquiry.

The response should identify which of those factual predicates DHS actually contests and answer them with the most reliable incident specific evidence. Matter of Davey and Matter of Dominguez-Rodriguez make the factual scope of the occasion important, so the briefing should not assume the judgment alone resolves quantity or personal use.

Build the Incident Record, Not Just the Conviction Record

The useful file is the record of the particular marijuana incident. It should include the judgment, charging papers, plea materials, laboratory or property reports showing weight, police inventory records, paraphernalia evidence, and any reliable admissions or testimony bearing on personal use. If more than one count arose from the same episode, the documents should show whether they concern one occasion or distinct conduct.

Quantity evidence should identify whether the stated weight is marijuana itself, a mixture, or packaging. Evidence suggesting distribution should be separated from evidence that merely shows possession, because the exception turns on the actual character of the conduct rather than the seriousness of the criminal label.

Do Not Treat “One Case” or “Small Amount” as the Legal Test

A single criminal case can contain more than one immigration relevant offense, and a relatively small amount does not by itself establish personal use. The statutory exception is narrower than either shortcut. Counsel should ask what conduct occurred on the occasion, how much marijuana was involved, whether possession was for the respondent's own use, and whether any companion offense changes that characterization.

The reverse mistake is also possible: a paraphernalia or possession related count arising from the same minor incident does not automatically defeat the exception. The controlling inquiry comes from the statutory limits and the BIA's circumstance specific cases, not from the number of docket entries.

Prove the Four Limiting Facts of the Exception

A focused presentation can be organized around four propositions: the respondent had a single qualifying offense, the conduct was possession rather than distribution, the possession was for personal use, and the amount did not exceed 30 grams. Each proposition should be tied to a specific record source instead of being left as a conclusion.

If DHS relies on companion conduct, the response should explain whether that conduct occurred on the same occasion and whether it actually changes quantity or personal use. The strongest presentation is factual and narrow because the exception is itself a narrowly drawn statutory carveout.

What the Immigration Judge Must Find for the Exception to Apply

The decision should identify the incident and make findings on the statutory limits rather than simply label the conviction a marijuana case. The critical questions are whether there was a single offense, whether the conduct involved possession, whether that possession was for personal use, and whether the amount was 30 grams or less.

Where the record is incomplete, the parties should address who bears the relevant burden in the procedural posture and what evidence is legally available for the circumstance specific inquiry. Other drug related grounds should be analyzed separately so they do not blur the limited issue presented by §237(a)(2)(B)(i).

Primary Legal Authorities and Sources

Frequently Asked Questions

Does the exception require exactly one criminal count?
Not always. Matter of Davey allows closely related convictions from one qualifying incident if none is inherently more serious than simple possession.
Is the 30 gram question categorical?
No. BIA precedent treats this exception as circumstance specific.
Does distribution qualify?
The statutory exception is for possession for one's own use, not distribution or trafficking.
What if the judgment does not state the quantity?
Other credible and reliable evidence may be important to establish that the incident involved 30 grams or less.
Does this exception erase all marijuana immigration consequences?
No. Other immigration statutes and forms of relief have their own rules.
Does the 30-gram marijuana exception apply to every marijuana-related conviction?
No. The statutory exception is limited to a single offense involving possession for the respondent’s own use of 30 grams or less of marijuana, and precedent limits the exception where additional offense elements materially change the conduct.
