I'm going with things vegans would avoid instead, because you could go on forever with things that a vegan *could* drink.: *Some red/pink colored soda or sugary drinks like Kool Ade might have coloring in them that isn't vegan. *Some beer, wine, & liquor is refined using isinglass, gelatin or other animal products. http://barnoivore.com is a good place to find out if your favorites are vegan or not. And of course things like Bailey's aren't vegan, but you can make your own Bailey's at home if you like it. I've seen recipes online.
Marijuana can stay in the urine for up to two months in cases of very frequent, prolonged use. Basically, the more you use marijuana, the longer it will remain in your urine. If you have just tried marijuana, for example, and that was your only use, it will probably be out of your urine within a week.
Marijuana has a half-life in your system. How long it takes to leave your system depends on how much you smoke. But the time maxes out at around 45 days. One smoking session for someone with a clean system takes about 3-4 days to be clean. Smoke 2 days later and then have to wait about a week, and so on.ou are good. From wikipedia http://en.wikipedia.org/wiki/Drug_test#S... Saliva / oral fluid-based drug tests can generally detect use during the previous few hours to 1â2 days. THC may only be detectable for less than 12.0 hours in most cases.
