Pulse Analysis

The Supreme Court’s jurisprudence on religious use of controlled substances began with *Employment Division v. Smith*, where the Court upheld a ban on peyote despite sincere Native American worship. That decision was later softened by *Gonzales v. O Centro Espirita Beneficente União do Vegetal*, which recognized a narrow RFRA exemption for ayahuasca‑using members of a Brazilian‑origin sect. The ruling emphasized that the government must use the least restrictive means when burdening sincere religious practice, creating a legal foothold for future challenges involving hallucinogenic sacraments.

In the recent Hemani case, Justice Kagan’s hypothetical thrust the ayahuasca exemption into the Second Amendment arena. She suggested that Congress might prohibit firearm possession for users whose reality “dissolves” under the drug’s influence, raising the question of whether such a categorical ban would survive the Court’s historical‑tradition test. The interplay between the Free Exercise Clause and the Second Amendment could produce a hybrid right, where religious liberty reinforces gun‑ownership protections, or it could allow the government to impose a tailored restriction if it passes strict scrutiny under RFRA.

The outcome will reverberate beyond the niche of ayahuasca practitioners. A decision that bars religious drug users from owning guns could set a precedent for broader firearm regulations tied to substance use, potentially affecting veterans, medical cannabis patients, and other groups with federally prohibited yet medically or spiritually significant substances. Conversely, a ruling that upholds the exemption would reaffirm the Court’s commitment to narrow, least‑restrictive‑means analyses, reinforcing the protective shield around sincere religious practices even when they intersect with contentious policy areas like gun control.
