Please pick two types of drugs and explain how they may affect individuals
Weegy: LSD, PCP, and Ecstasy are examples of hallucinogens, and these drugs have the ability to affect a person's perceptions dramatically. Information travels through the brain at rapid speeds and is carried by chemical messengers called neurotransmitters. [ Hallucinogens interfere with the function of neurotransmitters, which interferes with the speed at which messages travel. Hallucinogens also alter the function of the nerve cells in the brain by destroying the brain's nerve fibers. ] (More)

Weegy: Stimulants Stimulants are drugs that stimulate the Central Nervous System. These substances tend to increase alertness and physical activity. They include Amphetamines, Cocaine, Crack and some inhalants like Amyl or Butyl Nitrites. [ Caffeine (present in tea, coffee and many soft drinks) is also a mild stimulant drug. Which stimulants are abused? The most widely abused stimulants are cocaine, crack (a pure form of cocaine) and amphetamines. Cocaine has limited commercial use and its sale and possession are strictly controlled. Nevertheless there is a huge worldwide illicit network for the manufacture and supply of this drug in its various forms. Doctors sometimes prescribe pharmaceutical amphetamines and their availability makes them candidates for misuse but powdered amphetamine, manufactured in illicit laboratories, is the most common type of amphetamine to be abused in the UK. Inhalants such as amyl and butyl nitrates are legal at present. Because of their very short action time - the effect lasts approximately 1-2 minutes - they are usually only abused in certain settings, such as parties etc. What do they look like? Stimulants appear in many forms. Pharmaceutical amphetamines are usually produced as pills or capsules, whereas street amphetamines come in the form of a fine, white dull powder. Inhalants can be prescribed or purchased in small glass vials which are crushed to release the vaporising fluid inside, or in small bottles. Cocaine is a relatively fine, white crystalline powder. Crack is seen as cloudy white crystals that are irregular and fairly large (pea-sized). What are the effects of stimulants? Different stimulants act on the body in different ways. For example, nitrate inhalants cause the blood vessels to dilate (widen); cocaine and crack interfere with normal levels of the neurotransmitter serotin; amphetamines cause the release of adrenalin. Nevertheless, broadly speaking all these stimulants have a similar effect in that they ... (More)
