This man was a meth addict not an alcoholic. He might have been an alcoholic, too, but he was arrested for meth.
While many drugs, such as cocaine and heroin, fuel addiction by mimicking a neurotransmitter and teaching your brain to crave them, meth is slightly different. Meth actually imitates dopamine and norepinephrine, the pleasure-inducing and alertness-inducing chemicals in the brain. Every time you smoke, snort, or inject methamphetamine, your brain is triggered to release more of these chemicals naturally, until it eventually breaks down and loses the ability to produce them in adequate levels. So in order to feel high and even to stay awake, addicts need more and more meth. This is why a meth user coming off the drug will typically be volatile and may sleep for days at a time. While on the drug, meth users report feelings of confidence, euphoria, invincibility, and increased sexual drive. But meth soon burns up their bodies’ resources until they depend on it to function.
The number of meth addicts who remain sober at least three years after treatment hovers at 12 percent. Experts attribute the low number to several factors, including the lack of understanding of how meth addiction rehab is unlike rehab for other drugs, such as cocaine and heroin.
Without the benefit of rehab, the recovery rate for meth addiction drops from 12 percent to merely 5 percent.
