I have no problem with marijuana being prescribed as a drug for cancer etc. There are many drugs that cause horrible things to happen to people when not used in a regulated way. That's why you can only get them with a prescription. I don't get why marijuana can't be treated the same way. Perhaps someone can explain this to me.
The reason they can't perscribe marijuana is because it varries so much from one batch to another. There is no quality control. Some batches may be normal and some my be super strong depending on how & where it is grown. I have friends whose offspring (and some not so young -- some of them now 50 years old) have made total messes of their lives over use of this drug. When you get close enough to inquire what happened to this formerly handsome, bright, educated young man (who is now schlepping around living off his folks) invariably it goes back to pot use.
