Have you ever been afraid of what your doing?

It dawned on me the other day I wasn’t as concerned about the legality, health effects and work repercussions as I used to be. So I was wondering if there is a tipping point that one reaches when doing drugs?<br><br>For me it’s the level of tolerance. When I notice a big shift in tolerance, I start to take a closer look at my habits. <br><br>Do you think anyone can reach this tipping point or is it particular for certain drugs and lifestyles?
