The proportion of inmates in jails with a moderate to severe stimulant use disorder—including addiction to methamphetamine—has surged in recent years, a study presented at the recent American Society of Addiction Medicine annual meeting suggests.
A new study suggests restrictions put into place by the U.S. government on a chemical needed to produce cocaine have led to a reduced use of the drug in the past decade. Mexican police action against a company importing pseudoephedrine, which is used to make meth, also contributed to the decline.
People addicted to methamphetamine may be helped by exercise along with addiction counseling, a new small study suggests. The researchers report exercise increased the number of dopamine receptors in the brain, which can lower the desire for the drug.
