They also save more lives.
What was almost-certain death, before penicillin and the later super antibiotics, is now a nuisance of remembering to take the medicine long after you're well.
I defy anyone to claim the same for pot, hashish, methamphetamine, heroin, opium, LSD, "bath salts" or any other recreational drug taken to scramble the mind.
Nice try there, but no cigar.
Please limit the discussion to marijuana.
A close friend suffers bad lumbar area pain in his back. He tried everything.
His date's sister made "Tootsie Rolls" with marijuana for a Jeff Beck concert.
He woke up for work the next morning still stoned...but he realized then and even for another 24 hours, his back pain was gone.
Personally, as a seasoned citizen, my appetite for food suffers badly. When I mentioned this to my primary doctor, he offered to write me a prescription for medicinal marijuana. LOL
I neglected to take him up on the offer.
My friends and family got a good laugh at that one.
