What it feels like
Meth stimulates your central nervous system to release a large amount of dopamine, a ‘feel-good’ brain chemical. This can make you feel energetic, alert, talkative, and confident. It can also increase your sex drive, and reduce your appetite. If you have a lot or use for a long time without sleep, users can feel agitated, experience mood swings, and see, hear, or feel things that aren’t there (hallucinations).
How to be safer
All drug use brings a risk of harm. Injecting any drug is very risky, especially when needles and injecting equipment (e.g. swabs, needles, and spoons) are shared. Risks include infections such as HIV, hepatitis C, and sepsis, a bacterial infection of your injecting wound. Injecting can also lead to skin abscesses and collapsed veins. Using a wheel filter can help to remove impurities that cause infections.
Use soap and water or alcohol swabs to clean your hands before using. Use your own mouthpiece or pipe to reduce risk of infections.
Use a shatterproof Pyrex pipe. Other pipes (or glass) can get too hot or give off toxic fumes. Avoid using broken or cracked pipes. Damaged pipes can lead to burns, cuts and infections.
Smoking or snorting meth can cause your lips to become dried and cracked, or nose to bleed. This means increased risk of infections, especially when utensils are shared.
Mixing drugs is always risky because it is hard to predict how one drug will affect another in your system. See our Drug interactions section for more about the effects of mixing meth with other drugs.
Take extra care to practice safe sex because meth may increase your sexual desire while decreasing your ability to make good judgements.
