How long till you get addicted on meth?

It takes about only one time taking it --- As with any drug, it depends on the person. Some people have a higher risk of chemical dependency than others. Meth is one of the most addictive drugs available, so the likelihood of becoming addicted is much higher. After using it once, some people will have a strong desire to use it again and will use it again, and will repeat this pattern until they develop a full-fledged dependency. Other people can use meth on a recreational basis and cease use without any problems.
