Attending a drug rehab may be necessary when a person is severely addicted to drugs or alcohol and wants help to stop using. Most people attempt to stop taking drugs on their own and some succeed. Unfortunately, many severe drug abusers find that it is not as easy as they anticipated, achieving abstinence and they end up using again. You should of course attempt to stop on your own first and if that fails enrolling into a treatment program would be the next option. From 1898 through to 1910 heroin was marketed as a non-addictive morphine substitute and cough suppressant. Bayer marketed heroin as a cure for morphine addiction before it was discovered that heroin is rapidly metabolized into morphine, and as such, "heroin" was basically only a quicker acting form of morphine. The company was somewhat embarrassed by this new finding and it became a historical blunder for Bayer. Short-term effects of marijuana use include memory loss, distorted perception, trouble with thinking and problem solving, and anxiety. Students who use marijuana may find it hard to learn, thus jeopardizing their ability to achieve their full potential. By the turn of the twentieth century, the addictive properties of cocaine had become clear, and the problem of cocaine abuse began to capture public attention in the United States. |
