People who grew up in the 1980s were very well versed in the doctrine behind the D.A.R.E. Program. Nancy Reagan, who was the First Lady at that time, spearheaded the campaign. Her slogan was, Just Say No, and it was one that every elementary school child heard almost every day. The program taught children that the use of drugs like marijuana would definitely lead to the use of harder drugs, eventually.
Today, scientists are still debating whether or not the gateway drug theory holds any weight. Many claim that the use of some types of drugs actually keeps people from trying harder ones. Eventually, people involved with the D.A.R.E. Program even admitted that this could be the case.
Even so, the theory may be making a comeback in recent years. The legalization of marijuana and the heavy use of opioid drugs has people questioning the root cause of addiction.
One study that was published from Columbia University showed some interesting information about rats exposed to alcohol. They found that those rats were much more likely to press a lever that released cocaine than those that weren’t exposed. They also found that the alcohol was able to suppress two different genes that usually act as “cutoff switches” for the effects of cocaine. This worked to create a more permissive environment in the rats’ brains.
Other studies that have been done have led scientists to a very interesting conclusion. Dr. Kandel, who is a professor of sociology at Columbia University stated, “Now that we’ve done the animal experiment, we see that using one drug changes your brain in such a way that using another drug becomes more rewarding. And there is an order.”
When rats were exposed to cocaine first, using it didn’t automatically cause them to press the lever for alcohol. This indicates that the less dangerous drug, indeed, led them to have a desire for the more dangerous one.
