Gateway Drugs: Do They Exist?

The idea of gateway drugs is controversial in the health and social sciences fields: is there such a thing as a gateway drug? Are cigarettes, alcohol, marijuana or even caffeine gateway drugs? Is the effect on the user social, biological or coincidental?

What are Gateway Drugs?

A gateway drug is a controlled substance that presumably leads the user to harder, more dangerous drugs or dependence on illicit drugs. The list of gateway drugs has grown in the last few decades; initially alcohol, marijuana and tobacco were the primary drugs that led to more severe drug use. In the recent past, with the growing popularity of prescription drug abuse, medications such as Vicodin and Ritalin have been added to the gateway drugs category. Some have even suggested that caffeine may be a gateway drug; however, no evidence has been proven to substantiate that claim.

Gateway Drug Theories

There have been numerous studies conducted across the world that have tried to determine the truth or myth behind gateway drugs. Studies included the use of marijuana or THC, the main element in marijuana, alcohol, amphetamines, and tobacco. Some of the hypotheses were that there were chemical changes in the brain, that impulses were altered with gateway drugs or that the sensitivities were modified with the initial use of particular substances. There were varying outcomes but most did not prove a direct correlation between early use of “gateway drugs” and subsequent use of more illicit drugs or addiction.

Alternative Explanations to Gateway Drug Theories

Over the years and in response to several studies, a number of alternative explanations have been given to understand substance use and progression in adults and juveniles. The most accepted reason is that the environmental and psychological factors that lead to the initial drug or alcohol use, contribute to continued evolution of abuse and addiction. Another aspect is the user’s attitude toward controlled substance use and their willingness to take great risk. If a person does not see drug or alcohol use as dangerous, or they feel that the hazards have been exaggerated by society, they will be more likely to engage in this behavior. Lastly, it appears that those exposed to the illegal environment where they purchase alcohol or marijuana will bring them in contact and give them the opportunity to acquire harder and more illicit drugs.

The Answer to Drug Addiction

Addiction and Substance Abuse is a serious problem in America; the causes and factors that lead to dependence are many and complicated. The ideal environment for a person to avoid use of any substance is one filled with a positive community where they are encouraged, loved and valued. Unfortunately that is not always the circumstance. If you are concerned about the drug use of a loved one or yourself, please contact Casa Palmera.
