Don't do drugs. But if you have to, do the least amount as possible. Experiment with dosages.

Dosage of mushrooms containing psilocybin depends on the potency of the mushroom (the total psilocybin and psilocin content of the mushrooms), which varies significantly both between species and within the same species, but is typically around 0.5-2% of the dried weight of the mushroom. A typical dose of the rather common species, Psilocybe cubensis, is approximately 1 to 2 grams,[8] corresponding with 10 to 25 milligrams psilocybin and psilocin, while about 2½ to 5 grams,[8] dried material or 25 to 50 milligrams of psilocybin/psilocin is considered a heavy dose. Fresh mushrooms are approximately 90% water. Drying the mushrooms breaks down the psilocin much faster, thus shifting the psilocybin/psilocin ratio. Exposure to heat generally breaks down the psychoactive ingredients. When eaten dry, 1 to 1.5 grams of mushrooms provide a small "trip" that can last up to 3 hours. The effects then are relatively mild, depending on the tolerance of the subject. With 3 to 3.5 grams one experiences a strong and solid trip which can last more than 5 hours. source: http://en.wikipedia.org/wiki/Shrooms#Dosage do them someplace that you are very familiar with and know well.

I've never done them, but I know about 10 people who have. I would say (if they are real shrooms) to do all of your share (if you bought for 3 people do 1/3). If when buying them you didn't say how much you wanted they might have given you enough for 10 people. I don't know how much you have so I couldn't tell you. I would be careful- about 80% of the time what people sell as shrooms are really dried out grocery store mushrooms laced with LSD. It's much cheaper for the dealer, and those who haven't done LSD won't know the difference. Unless you really trust who hooked you up with them, I would sort of expect them to be normal mushrooms with LSD. If they are them I would only take a little bit and wait an hour, and if you don't feel anything do more. If I were going to do them I would do it in my own house. If you are in an unfamiliar area, you might freak out. I would pay or ask someone to babysit (watch over) me, so that if I do freak out or if it's LSD and you are ODing they can take you to a hospital or calm you down. I would also keep some sleeping pills and maybe some weed handy, because if you are having a really bad trip and you want to sleep it off instead of tripping off your ass you could take a few sleeping pills and smoke some weed so that you would pass out. Think happy thoughts before hand, so that your trip will probably be good. Have fun. Don't call the cops on yourself.

Do 1/8 of an ounce (I assume you have mostly caps) the first time. Chew them good (they taste horrible) and wait about 45 min for them to kick in. You may vomit the first time, but don't worry, this can be normal. I reccomend being in a relaxed atmosphere with as few people as possible and don't plan on doing anything important for about 6 hours. Happy tripping :)

I really like Auntie Em's answer best, but if your really set on it: For your first time: try a 1/2 gram to a gram, no more, with your best friends only, they will take care of you if anything goes wrong,(remember shrooms ARE a fungus) and where you can just chill with no pressure, safely, listening to good music.

without advocating the use of drugs, i will say that you should be very careful if you choose to do those. like grammy robin, i suggest starting with a very small amount in case you have a bad reaction. has anybody you know tried any of these mushrooms? (i don't just mean the same type, but ones from the same batch.) cuz there are fatally poiseniness ones that look a lot look the hallucigenic kind! also, a good environment would likely include someone sober, a friend who can help "guide" you through your trip, no crowds are people you don't want to know you're on drugs, and a lot of people think the outdoors is best.

This is why I prefer to make tea or kool aid out of them. Boil about 3 grams in some water and mash all the liquid out- save the liquid. Mix it with about 1/2 cup sugar and add water to make it about 2 cups. Add about 1/2 package of Kool-Aid to it. You want it to be stronger than normal Kool-aid to combat the horrid taste. Drink 1 cup of it... you should get the same dosage out of 1 cup of your mixture as 1 1/2 grams of the shrooms. Wait about 30-45 minutes and if you don't like the effects, don't drink any more. If you feel them but they are too weak you can drink the other cup and get a nice strong trip. If you drink the first cup and you like the way it feels, then you can split the other cup in half and drink it in 1-2 hour intervals to extend your trip. As everyone else said, be in a comfortable situation with friends. Have some good music. Don't make any other plans for the day so that you don't get stressed out. Stay in your element the first time... you might like to go on adventures when you are more experienced with the effects of hallucinogens, but at first you should stay in one place. Nausea is sometimes normal... but it should pass. Don't mix with other drugs- especially since you are inexperienced. Be safe, have fun, and enjoy.

For your first time take only one gram. Species differ in size - the amount of mushrooms per gram will vary("how many" cannot be answered). It depends on species but anywhere from 1-5 grams is a standard dose. You can always take more after an hour or so if it isn't enough. It can take anywhere from half an hour to an hour for you to notice anything. Depending on when your last meal was it can take longer. Try not to eat for a few hours before taking them. Usually effects will last about six hours but some experience sleeplessness for a few additional hours. Many people just chew them. Other options are to crush them and add them to orange juice or my favorite yogurt. Nausea is experienced by most people after ingestion. Many people prefer the tea method, preparing a tea is a great way to avoid the unwanted nausea. There are a few ways to do this: ¤ Mushroom Tea ¤ Cook about 2 grams of dried magic mushrooms with some water. Cook the water slowly, keep the fire low and leave the magic mushrooms in for about 20 min. Pour the water and mix with a caffeine-free tea. Drink the Mushroom Tea http://drugsrus.wordpress.com/2007/02/17/magic-mushroom-tea/ http://www.erowid.org/plants/mushrooms/mushrooms_prep2.shtml http://www.magic-mushrooms.net/paddos/Drinks__mushroom_tea.html If your are emotionally unstable do not take them. Take them with people you trust. Try to find the most comfortable setting you can. http://www.erowid.org/plants/mushrooms/

Of course you should be in a comfortable environment, preferably with friends. Something like camping would be a fun experience. Limited contact with other people is always a good thing. My advice on the taste: Eat them with peanut butter. Its easy, quick, and you cant taste a thing. If its the texture that bothers you, eat peanuts.

haha do them in the woods with some friends.

Do them at a NASCAR race of WWF match?
