Being stoned can be quite an exhilarating experience for those green to the Green. But how can the new pot smoker judge whether or not they are intoxicated? There are a multitude of effects that marijuana causes, depending on dosage and potency. As a rule, though, the less you smoke, the less you feel the effects.
Many regular bud smokers report that they feel rolling stages of being high: first comes euphoria and giddiness, and with that the Giggles sometimes. Early on in the high, a surprising sensation called cottonmouth or dry mouth almost always comes into play. Cottonmouth feels like a persistent dry mouth, making the pot smoker want something, anything to drink. Saliva dries out and becomes more viscous. After about 15 minutes, the feeling subsides. During this time slight hallucinations may occur, usually in the form of ethereal things like non-existent puffs of smoke and feeling droplets of water hitting skin. Inexperienced users and smokers of odd varieties may also feel an unusual very slight dull pain in the extremities. I'm not sure where this comes from. It might be from evil additives, which concerns me.
Riding the high:
Oftentimes, after 15 minutes or so, a sense of happiness, tranquility and sedation sets in. Depending on the potency of the weed smoked, this time can last from 20 minutes to a few hours. In large enough doses, the user may become confused, and possibly paranoid. Perceptions of reality may become somewhat warped. It is well-known that smoking weed can temporarily impair depth perception. The senses seem elevated. Memory may become fuzzy, and holding a linear train of thought gets very difficult. In particular it may be difficult to recall the time when one was stoned.
Some believe that weed makes you horny, but in fact, it seems to strip down inhibitions to things that already existed, perhaps making people truer to themselves. This may make first-time users nervous, as a loss of self-control can be very uncomfortable. Many people feel more creative and imaginative when high, though from the outside they may be saying silly non sequiturs while trying to sound profound. Heavy users, in particular, may appear to have bloodshot, irritated eyes while stoned. Virtually anyone who has tried weed more than a handful of times has experienced the munchies, a craving usually for snack food.
Some people have experienced nausea, possibly vomiting, panic, depression, rapid heart beat and high blood pressure. This sort of thing has been observed in laboratories, but in Real World Experience (TM) I have not yet seen serious problems with this.
Lastly, if you are smoking schwag (inferior marijuana) you may barely experience any of the interesting effects above, and may simply get really tired, which can be an annoying waste of money. Your mileage may vary, moderate and you'll probably be OK.
