Interesting about drugs, thus I Think mostly of alcohol and Tobacco.
My story:
I've Always been a clean living person, going to the gym, eating salads and such, my only load was candy and bad foods at times.
Now, lately a bad person contacted me of opposite gender and a weird relationship sat in. This made me try to calm my nerves with alcohol and smoking at times. I was far from a big consumer, we're talking a few glasses of wine perhaps once every other week but keep in mind I usually dont drink ANY alcohol at all. But when it got too much, I went for it.
My friends, who have known me for a long time and know how much of a health freak I am since I find if interesting, a challenge and fun, to keep myself fit and the body as clean as possible from all sorts of toxins, reacted and went -YOU'RE DRINKING and SMOKING?? What in the actual f...? They couldnt Believe it and some mof them actually had to see it to believe it.
I was surprised by this urge myself BUT; it did calm me down and when sober again I looked at it a different way and told myself to "Cut if off, this guy's FAR from good for you, look at what the relationship with this guy is making you do".
Not saying it was his fault I drank and smoked because that was my poor choice but he was the CAUSE.
I have now broken it off once and for all and blocked him on all instances and the craving to drink and smoke is like before: non existant.
Conclusion:
Thus I suspect if it's the same for others, could doing drugs be a way to try and calm ones nerves down?
