I got a job at a midsize engineering firm. Can I rip bongs?

Nothing said about a drug test on website, job application, during interview, job offer letter, or whenever I talked to my future boss. May I rip mad bongs now in celebration?

Depends on where you live. It is illegal in some countries.

Do it. Congradulate yourself ;)
Sure...go ahead. Go to your new job wasted! That'll get you noticed!
Ive got a mate who does at work in his car in the carpark
not that im saying you should it depends on if you get caught and what your job means to you
Many companies drug test on hiring but do not after you are employed unless you are screwing up. Get a prescription from your Dr. and it probably wouldn't matter anyway. They can fire you for any reason anyway so rip on. I am a retired engineer and usually saved that for after work...Dr.s orders!
