The Board of Immigration Appeals (BIA) has determined that “where an alien has been convicted of violating a state drug statute that includes a controlled substance that is not on the federal controlled substances schedules, he or she must establish a realistic probability that the state would actually apply the language of the statute to prosecute conduct involving that substance in order to avoid the immigration consequences of such a conviction.” In the instant case, the respondent argued that a Florida conviction for possession of marijuana did not render him inadmissible because Florida’s definition of marijuana is broader than the federal definition. “The respondent has also not presented any cases where a defendant was successfully prosecuted under Florida law for an offense that involved only a form of marijuana that was not prohibited by 21 U.S.C. § 802(16).” As such, the BIA found that the respondent had not established a realistic probability that Florida prosecutes marijuana offenses that fall outside the federal definition of marijuana.
