Thats actually my point @sandzat Marijuana is a natural plant known to heal and cure cancers yet its use is suppressed because of big pharma. As for long term effects I have many friends that have smoked for a very long time and are in excellent health, physically and mentally. Im an occasional smoker. I dont really like the feeling of smoking anything but im certainly interested in Marijuana Oil. One of my friends was an original grower back in the 80s in Mendocino, Cali. He has smoked his whole life since being a teen. He's now in his 50s and fit as a fiddle. Thats the evidence I have personally witnessed of long term effects.
