The fact that your mom was an addict makes the potential for you higher. My dad was an alcoholic and me and my brother both became alcoholics. The other two kids didn't. Of course if I had never drank or used then the genetics wouldn't have meant anything, I couldn't have become one.

While weed is the least addictive of all of them that doesn't mean you can't be addicted. I was a pot head for many years and for sure was addicted. I would try to quit drinking and would end up smoking three times as much pot. Then I would get so burnt out and my tolerance was so high I would start drinking again. The last five years I was snorting meth very heavily and I didn't care one bit about drinking or pot. It filled the bill. Of course that didn't end good. Back then they didn't drug test.

Yes I think you should be worried. The fact you don't like alcohol is in your favor but you can get used to it real fast. I personally don't believe in drug tests because it is none of their damn business what I do after work and pot can take 30 to 60 days to show up negative. I haven't had to worry about it because I have been clean and sober for many years. I know lots of guys who struggle with that issue though.
