We need to move beyond the area where abused drugs are used for medicine, and work on safer methods.
If there's elements of pot that is helpful, isolate them. Keep all the addictive parts out of it.
It's a dangerous road though, since this is all about getting high in the first place.

Personally I am a fan of herbal remedies. They are much less taxing on your body and have very positive effects.
Then try toadstools.
