Risks
Meth is a high strength amphetamine, putting high strain on the heart and increases blood pressure. It is common to feel heart palpitations when under the influence of meth. The risk of heart attack and stroke are increased.
Injections carry the risk of HIV and hepatitis C infections if needles and syringes are reused and shared between users.
It is also not processed by the body and therefore it is possible for people to get high from drinking the urine of someone who has taken meth (referred to as chempiss).
Because of the strong effect of meth, the comedown is often severe. It may not be possible sleep for a few days after using. People may experience paranoia and hallucinations. Ongoing use can cause psychosis and even brain damage.
Drug interactions
Stimulants such as caffeine can accelerate the effects of meth.
Addiction
Meth is psychologically and physically addictive.
Risk mitigation
Smoking meth is generally considered a lower risk than injecting.
Fresh needles and syringes should be used for each injection and not shared. Injection water should be used to reduce the risk of infection, as tap water is not clean enough to inject into the body.
Monitor for adequate hydration by observing the color of the user's urine.
As a stimulant meth can suppress the user's appetite. Protein shakes, rehydration powder, and vitamin tablets may be consumed to stay nourished. Attention must be paid to avoid overeating.
The comedown can be rough, and may take a long time. Do not drive or operate machinery until safe to do so. Watching gentle television programs and cartoons may help to wait out the comedown, avoid things with action and excitement. Having a companion to to provide social interaction and supervision can mitigate some parts of the comedown.
If use is affecting work, social life, and relationships, seek advice from a drug counseling service.
