Methamphetamine and Health

Undoubtedly prolonged and regular use of any drug can have serious health effects.
 
Whether the effects commonly  attributed to Methamphetamine, and particularly to smokeable Crystal Meth, such as those shown here are due to the drug itself or to the lifestyle are open to question.

Long-term methamphetamine use has many potentially negative consequences, including: extreme weight loss (through long term loss of appetite and generally poor nutrition); dental problems (whether this is through poor dental hygiene or a sided effect of the drug itself is open to question); agitation through over-stimulation (tweaking); insomnia, mood disturbances, and possibly an increase in violent behaviour.

Chronic methamphetamine users can also display a number of psychotic features, including paranoia, visual and auditory hallucinations, and delusions (for example, the sensation of insects creeping under the skin). Again how much of this is due to the effects of the drug and how much to chronic insomnia is debateable.

There are also concerns about the effects of methamphetamine on the transmission and progression of sexually transmitted and blood-borne viruses. Among meth users who inject the drug, HIV, Hep B and Hep C and other infectious diseases can be spread through contaminated needles, syringes, and other injection equipment that is used by more than one person. The effects of methamphetamine, can also alter judgment and inhibition and lead people to engage in unsafe sexual practices. Methamphetamine use may also worsen the progression of HIV and its consequences. Studies of methamphetamine abusers who are HIV positive indicate that the HIV causes greater neuronal injury and cognitive impairment compared with HIV-positive people who do not use the drug.
