I've taken drugs almost everyday,on and off for nearly 30 years. During that time,I've had multiple jobs. Studied and gained qualifications at varying levels aswell as vocational qualifications. I am qualified to drive forklift trucks,qualified as a chef,to work as a mystery customer and have worked in customer service for Asda (Walmart) and house of fraser (Harrods).
Providing my supply was uninterrupted,nobody was any the wiser.
I worked like a crazy dog. Never took days off and did a ton of overtime to support my home and family aswell as my horrendous drug habit. So yes,it can be done,but it really isn't any kind of life.
Years back I was doing crystal meth..I was super man on the job for awhile there.But It caught up with me after long.Everything fell apart around me.I was so exhausted and have crazy after awhile,I couldn't make it to work anymore.I been off that shit over 15 years now,thank God.Crystal meth is the devil.
Methamphetamine is quite uncommon here,in the UK. I'm very grateful for that after seeing what it's done in the states.
