Can I pretend to travel for work so that I can have time to  experiment with drugs?
Why do you want to experiement with drugs?
I love watching people have fun with drugs. Drugs bring so much fun to their lives.
This behavior will get you in trouble. It is bad to do drugs and it is bad to lie to your employer. You should rethink your decisions.
I'm not worried about getting in trouble at work or becoming a hardcore druggie. I think the drugs will make traveling more exciting, and my boss will never know I'm not working.
If you do drugs you could end up in jail somewhere while traveling and you could lose your job. It is best to stay clean, and go to work when you're supposed to.
