Methamphetamine : Methamphetamine is a really nasty drug. If you live with someone on meth, you are familiar with the roller coaster ride. I recommend that you look into a group called alanon, it is for people who have loved ones who are addicted to drugs or alcohol. It will provide you with support, insight, coping skills and ideas on how to approach this. Take care.

Common effects: Not everybody on methamphetamine is happy and gets along - some people become violent, aggressive and psychotic and paranoid under the influence. However, when people are coming down, depression, anger and acting-out are common. This is a highly destructive drug, both physically and mentally. People on it need formal treatment programs and can rarely stop on their own. Get help for both you;them.
