I would probably be considered an amateour as far as you guys go, but i have done my fair ammount of research and have a fair ammount of knowlege on the subject. i have been smoking consistently for 4 years now at the age of 20. There is no question marijuana has some effects on life, but guess what everyone has these vices, joggers, workaholics, alchaholics, and so on. Marijuana is without question the least harmful, amoung drugs that someone can use. IM not gonna run through the numbers with all of you but think about.... espcially you medicine man... if you could do it all over again, and not take that first hit of weed... would you?
