I'm no chemist or college student, but I am a 14 year veteran smoker of the SPECIAL Cannabis plant! Here is what I can share from EXPERIENCE. Drug is only a word in a written dictionary created by humans so really in a higher sense it means absolutely nothing. It's just a way to identify something. Drug dealer has already been THOROUGHLY explained in someone's earlier post. If you didn't see it read again & then again! It's there - It couldn't be explained better. As far as human relation to the Cannabis plant - it is in my opinion very important to us and I'll explain why. Animals & humans show distinct differences in their sexes generally speaking correct? Guess what plant is one of the only in the WORLD that has striking differences between male & female. There are others that do, but not like this one. It's the Cannabis/Hemp plant. Coincidence - I think not. The prohibition involves much much more than just the pharma. companies. A Cannabis/Hemp plant could save the world, but it would cause economic disater for all big business. This one plant could grow almost anywhere so there would be tons & tons of it(no shortages). You could make - ready - paper,clothes,fuel,food, beverages, rope, etc. The list just goes on & on. Hemp fiber is the strongest natural fiber in the world. Hemp seed is loaded with all types of great nutrients. Smoking is great, but eating the products of the Cannabis/Hemp plant properly prepared is extremely benificial to your health & can get you baked if you make certain recipes. My believes on smoking everyday( I consumed/smoked well over 20 lbs. of Cannabis in my life). It does effect short term memory, but only temporarily - It does take some lung power away if your a heavy smoker, but nothing drastic. It definately allows the mind to be more open & understanding to different ideas & concepts. Overall with reasonable use - NOT ABUSE - it's as helpful as any other beneficial plant if not more. Of note I only been really sick once since I started using & I never take pain pills or any other pill or vitamin. I eat right, cosume Cannabis, & think for myself. These are some important things to remember for well being. One love!
