I am not sure about the context, but "drug therapy" would suggest that a more formal term should be used (like "intoxicated" or "euphoric")
As for slang expressions, have a look at
I always suspected there was an abundance of ways to express this condition, but I was still awed :o)

Description and source: Derived from the \"Cannabis Sativa\" plant. Delta-9-tetrahydrocannabinol (THC) is the most active cannabinoid in marijuana.
Common names: bhang, bud, cannabis, cucaracha, Doobie, dope, duby, funny stuff, ganga, grass, green, hash, hashish, hemp, hit, J, jay, joint, joy weed, **keif**, lid, marihuana, marijuana, Mary Jane, merry weaver, MJ, numbers, pot, Rasta weed, reefer, roach, shit, Sinsemilla, stuff, tea, THC, weed.
Abuse potential: **High**; habituation, but not physical addiction.
Method of administration: Smoking (22% uptake) and eating (95% uptake).
Effect at usual levels: Euphoria, sedation, temporal distortion, sexual arousal. Studies show functional impairment for 4-6 hours and possibly as long as 24 hours after a **single \"high.\" **
Based on the above, I withdraw my suggestion of \"high\" not being medicinal enough :o)
keif, keyf, kaif, kif, Kiif, Qif
history of Persian mysticism, where it has traditionally been used not as a stimulant but as a spiritual soporific, producing a quiescence of the soul which is known as **keyf** or **kaif**, which translates as intoxication, carouse or placid enjoyment...\"
When I speak of drug addiction I do not refer to **keif**, marijuana or any preparation of hashish, mescaline, Bannistria caapi, LSD6, Sacred Mushrooms or any other drug of the hallucinogen group...
Qif: (neologism) hashish. (The actual arabic is **Kiif**)
