The Most Addictive Over the Counter Drugs

2. Sleeping Pills

Many individuals struggle to sleep and in turn, they rely on common sleeping aids. Once desperate for a good night's rest, many begin using sleeping aids on a regular basis. These pills are only intended for short-term use, which is why an addiction can develop so rapidly.

Users become reliant on these medications and quickly need them in order to sleep. Once abused for an extended period of time, extreme withdrawal symptoms develop. Some of the most common withdrawal effects include tremors, nausea, and sweating. In some cases, discontinuing use makes sleeping difficulties worse.

1. Asthma Inhalers

When suffering from asthma, the worry of not being able to breath is frightening. This is an addiction that has been off the radar until recently, with many teens and adults taking numerous puffs in order to get high. As one's blood pressure rises, dangerous side effects develop.

Although inhalers typically require a prescription, they are highly accessible. Within one study, it was found that some individuals would take extra puffs of their inhaler until they passed out. This was shocking to researchers, especially in terms of the self-reported rates of abuse.
