hmm... 167 pages and not a single "LEGALIZE IT". (Rest in pEACe Mr. Tosh.) http://youtu.be/ABc8ciT5QLs
To all those who can't see the green through their (big pharma wannabe) greed, cultivating marijuana will become legal and be re-introduced into the wild someday.

Your first problem is you're a vegan. Eat a steak and think clearly.

You're high on the animal's flesh/blood you inhaled and consumed.
If you wish to fully enjoy marijuana and live a long and healthy life, you should consider ending your addiction to blood.
Matter of opinion. I need carnitine so vegan diets just don't do it for me. I will say however my diet isn't heavy on meats, I eat a larger proportion of fruits and veggies than animal protein, but I still need some. I don't fully accept people can live without animal proteins for an extended period of time. Our biology isn't that of a herbivore.
