I don't project myself on others either. I'm not going to be one of these people who are always pointing out how bad drugs are for you. I feel like for me, the best approach is to "lead by example".
Same thing for my two teenage sons. I certainly can't go around and preach, "just say NO to drugs" when their mother is a drug addict. I can only hope and pray that they recognize the person I was on drugs, and remember how bad things got and how this sh!t impacted our lives. And recognize who I am nowadays...this woman that's their mom, who made the bad decision to get involved in drugs, whose now 200 days clean, and happier without the use of drugs, (even alcohol). I hope that they see that you can be happy without substances, and have a 'whole' life!
