In easier terms, it's not that easy to explain why people tend to use drugs again and again but even if people try to stop using drugs it's almost impossible for them to do so. 

To determine if someone is an addict takes a lot of time. Drug abuse is not a term that can be thrown around easily. It also depends on a lot of factors, such as if your condition is serious or not. If you're someone who regularly uses drugs then it is recommended that you perform the necessary steps to investigate your own drug abuse. 

How to Investigate?

It's important to remember that drug abuse is something that can be treated. Science has developed a lot over the last few years and there are a lot of rehab centers that are available for treatment purposes. 

The first step is to visit a psychiatrist or a psychologist. It's important to determine the reason behind your drug abuse. If you don't do this then you're bound to repeat your mistakes.
