If a landlord suspects a tenant is involved in drug trafficking, landlord under the REICO Act may be encumbered and needs to protect his/her own property and interests and can request a Criminal Background check on tenant and if tenant is truly involved in the drug trade that may be grounds for eviction. Landlord may also report suspicious activity to the authorities, however i'm unaware of the ability to require drug testing. If you're the landlord seek legal counsel. If you're the tenant seek legal counsel and cease illegal activities on the premises.
