Thank you Stas Novitsky, a person in long-term recovery, for much of the information on this page. I wish I had this back in 2010. 

Keep in mind that it’s a combination of many of these signs that illustrate a drug habit. This is not a complete list as substances to abuse are all over the place and around your house.

We could use the help of those in recovery to add to this. Use the comment box. You can use another name and only admin can see your email–no one else. Your privacy is respected.

There are a myriad of other drugs that can be abused such as Robitussin characterized by strange robotic movements, and even addiction to sniffing sharpie pens. Many times those with addictive disorder will also abuse many other substances including their drug of choice.

If you suspect your child or spouse is using, you can insist on a drug test and you can buy them online for less than your local drug store. But keep in mind, those who are using have all kinds of methods for hiding it, including using a friend’s pee, masking agents or abusing substances that cannot be detected by a drug test.

A drug test has never kept anyone from using but it does let you know what they are using if it’s detectable which can be handy in case of an emergency and setting your own boundaries.

What do you do? Find support for you, first. That could be a therapist for a couple to get on the same page or a group such as Families Anonymous. Resources here and it includes people whose kids are not yet addicted.
