Damn straight I believe that God gave us mushrooms (ok, not quite a plant) and pot and Ayahuasca and coca and even opium and I think that all of those are gifts from God that can be used or abused, just like any other gift.
Some people think the manna from heaven was actually magic mushrooms. Some also thing the herb that grew on Solomons grave was cannabis.
On the side of western medicine, if I didn't take Synthroid, a hormone, I'd be cold in the middle of July and sleep 12 hours a day, without flonase, a steroid, and others antihistamines life wouldn't be enjoyable in the spring, summer, and fall, and winter (I'm allergic to pollen in the spring and summer, and mold in the fall and winter. How unlucky am I? lol)
Without Propecia and Rogain, I'd be a bald 17 year old and we just can't have that With it I have a head full of thick hair. I'm dependent on all of these drugs but It's really worth it to enjoy life and it's not really a big inconvenience.
