(Federally-Subsidized Public Housing and Medical Cannabis) "In sum, PHAs [Public Housing Agencies] and owners may not grant reasonable accommodations that would allow tenants to grow, use, or otherwise possess, or distribute medical marijuana, even if in doing so tenants are complying with state laws authorizing medical marijuana-related conduct. Further, PHAs and owners must deny admission to those applicant households with individuals who are, at the time of consideration for admission, using marijuana. See 42 U.S.C. § 13661(b)(1)(A); Lester Memorandum at 2.
"We note, however, that PHAs and owners have statutorily-authorized discretion with respect to evicting or refraining from evicting current residents on account of their use of medical marijuana. See 42 U.S.C. § 13662(b)(1); Lester Memorandum at 5-7. If a PHA or owner desires to allow a resident who is currently using medical marijuana to remain as an occupant, the PHA or owner may do so as an exercise of that discretion, but not as reasonable accommodation. HUD regulations provide factors that PHAs and owners may consider when determining how to exercise their discretion to terminate tenancies because of current illegal drug use. See 24 C.F.R. § 966.4(1)(5)(vii)(B)(factors for PHAs); 5.852 (factors for PHAs and owners operating other assisted housing programs)."
