You'd probably change your mind as soon as you'd receive a devastating diagnosis, such as parkinson's.
if you knew, that nicotine could at least potentially arrest the progression, how sick would you need to get before you would try nicotine patches?
would you rather wait until you are unable to walk, talk, eat, wear adult diapers, but never ever attempt anything on your own?
"clinical recommendation" is nothing more than an OPINION, not some eternal dogma to be venerated.
Marijuana is being used medicinally en masse in many countries today. Still not a "clinical recommendation" in the US, and even an absolutely illegal drug with apparently no known medicinal use, but somehow thousands of epileptic kids manage to control their disease with Charlotte's Webb.
Strange how official "recommendation" can be total lies, no?
