Methamphetamine (crystal meth/ Tina)
- Methamphetamine (crystal) is a powerful amphetamine - an upper/ stimulant (speeding up the body’s reactions and functions).
- Other names include ‘Tina’, ‘meth’, ‘ice’, ‘crystal’, ‘crank’, ‘yaabaa’.
- Usually comes as colourless crystals; also a whitish powder/ pills (which may include a colourant).
- Under UK law the drug is classified as Class A (Misuse of Drugs Act 1971).
- Crystal releases the brain’s stress hormone norepinephrine and ‘feel-good’ chemicals dopamine and serotonin.
How it's taken
The time it takes to reach a desired high will often depend on your size, weight and metabolism; what you have already taken; and purity of the drug and the dose amount.
Reducing drug harm and risks | MEN R US
- Slamming injecting
The powder is dissolved in a liquid (eg: water) and injected into a vein.
The crystals are heated in a glass pipe and smoked.
- Snorting 'sniffed', 'keyed' or 'bumped'
Snorted up the nose in powder form through a straw or a rolled-up banknote.
- Booty bumps
Powder form dissolved in a liquid (eg: water), drawn up into a syringe without the needle, and injected up the arse hole. Alternatively, a finger is dabbed in the powder and then put up the arse hole.
Orally and swallowing 'bombing'
A finger is dabbed in the powder and rubbed it onto the gums inside your mouth. Alternatively, the powder is wrapped a toilet or cigarette paper and swallowed.
- Feeling alert, awake, confident, empathic, euphoric, full of energy, happy, disinhibited, (very) horny, an intense and focused sex drive, impulsive, sociable and talkative.
Sex on crystal
- Suppresses the need for sleep or eating, sometimes for days.
- May result in more extreme sex; eg: fisting and/ or involve 'riskier' sex you might not otherwise consider making
- Erections can be difficult/ impossible (also known as ‘crystal dick’). Some take erectile dysfunction medication to counteract this
- May result in compulsive/ repetitive wanking (masturbation) because you are so horny
- May be difficult and/ or impossible to shoot your load (orgasm)
- Longer and rougher sex can increase the likelihood of condom failure, and tears/ sores/ bleeding (cock/ arse/ dick/ mouth) which may not be noticed at the time.
- Less likely to feel pain
Using T and the comedown
- The comedown can feel overwhelming: exhaustion, tiredness, depression, difficulty sleeping/ chronic insomnia, difficulty focusing and/ or concentrating. Also, the strength of the comedown will be worse the more you use it.
- Aggressive behaviour, paranoia, and (in some cases) suicide.
- Not eating or lack of food can result in acid reflux and gastritis
- Crystal messes with your body temperature, increasing your heartbeat/ blood pressure, risking stroke, heart attack, coma and death
- Long(er) term use can result in obsessive/ repetitive behaviour, psychosis, paranoia, and long term mental health issues
- A high risk of psychological dependence, tolerance builds up quickly, and users need more to get the same high.
- It’s easy to keep using more... and become dependent
- High risk of psychological dependence, tolerance builds up quickly, and users need more to get the same high
- Slamming gives a faster rush but the high is usually shorter than say booty bumps or snorting
- Like other amphetamines, using crystal can result in memory loss, paranoia, and fits
- You can lose track of time, also forgetting to take your HIV medication on time, as prescribed
- Rubbing meph into your gums and can cause damage both to your gums and teeth
- Snorting meph can damage to your nasal passages and cause nose bleeds
- Nose, mouth and lung damage depending on how much you take
- Taking meph up the arse (booty bumping) can damage the lining of your anal canal increasing the risk of HIV, STI and HCV transmission
- Injecting can cause vein damage, vein collapse, sepsis (blood poisoning), and other infection (eg: ulcers, gangrene)
- Crystal can screw with your body's ability to regulate temperature leading in over-heating
- There are reports that a cocktail of crystal and other drugs can result in overdosing and death
- Check with your sexual health or HIV clinic.
