• A low to moderate dose of PCP can cause distinct changes in body awareness, similar to those associated with alcohol intoxication.
• Users may also experience shallow breathing, flushing, profuse sweating, generalised numbness of the extremities and poor muscular coordination.
• A high dose of PCP can cause hallucinations as well as seizures, coma, and death (though death more often results from accidental injury or suicide during PCP intoxication).

• Khat (Catha edulis Forsk, Celastraceae family) is a stimulant.
• Stimulant drugs speed up the messages going between the brain and the body.
• Other names for it include: qat, kat, chat
• The khat plant is a leafy green shrub that can grow to tree size. The leaves and buds of the khat plant are used.
• The fresh leaves and buds of the khat plant are chewed for their energising and stimulant effects.  Dried khat is commonly chewed and it can also be taken as a tea or smoked.

• Flashbacks sometimes happen. This is when part of the ‘trip’ is re-lived after the original experience. Flashbacks usually occur within weeks of taking LSD, but can be experienced months or occasionally even years later.
• People have been known to harm themselves during a bad trip. So people in a bad mood, feeling depressed or worried should avoid taking acid.

A good trip can make users feel relaxed and happy, with pleasant hallucinations. A bad trip can make you feel agitated and confused, with unpleasant and scary hallucinations. How the trip goes can be affected by your surroundings, who you’re with and how comfortable you are with them, and by your mood. If you don’t feel safe or comfortable, you’re more likely to have a bad trip.

• LSD stands for its chemical name, lysergic acid diethylamide, and is commonly called ‘acid’.
• It’s a powerful hallucinogenic drug – this means that users are likely to experience a distorted view of objects and reality, including seeing and sometimes hearing things that aren’t there (these are hallucinations).
• The experience of taking LSD is known as a ‘trip’. Trips can be good or bad, but until you take it you don’t know how it will affect you – and once it's started you can't stop it.
