Later research was not able to consistently find THIQs in the tissues of alcoholics compared to those of non-alcoholics. Actually, fetal alcohol syndrome babies are a major problem. While there are babies born of mothers who use cocaine or crack during pregnancy, most of these women also use other drugs and have other prenatal problems. Addicts cannot be medically treated. Actually, addicts are medically detoxified, when appropriate, in hospitals all the time.
Drugs have equal addiction potential.
It is logical to consider that every drug is not equally addicting. Obviously, all drugs are not the same in their site of action in the brain. Club drugs are new, not very dangerous, and unpredictable. We don't have much solid research on club drugs, but most have been around for 10-20 years or more. Emergency room reports indicate they are very dangerous, especially when mixed with alcohol.
