Mushrooms are an intense drug that grows from cow shit. Eat an eighth for an intense experience, make sure to have orange juice to wash it down. It takes about 45 minutes to kick in, and lasts about 6 hours. Your mind concerntrates on one subject for along time just trippin over it. You'll see alot of cool colors and designs wherever you go. There will be times where you laugh uncontrollably. Make sure to have lots of weed while shroomin, your body will absorb THC like no other. Some prefer the day, some prefer shroomin at night, I prefer both. After you're done, get a good nights rest.
