It has has been my direct experience, regarding alcohol, from AA, and addicts who are addicted to it, that withdrawal from alcohol is much more extreme, and life threatening, than withdrawal from heroine or crack or any of the hard "drug" substances. Withdrawal from alcohol can engender seizures and death.........not so with other drugs...........
Now, I've been "involved" with MJ since I was 42, and have done research on the stuff.........all I can say is that there were instances when these "plants" were used medically and spiritually by indiginous "DR.'s"/shamans/medicine men/women in the past with only good results.......
