Yes. This is something that needs to be discussed.
Almost every engineer is using some kind of stim in the morning and sedative in the evening. This can be as benign as caffeine/alcohol, but I've seen this escalate to any one of: caffeine, Provigil, cocaine, (meth)amphetamines on the front end, and alcohol, THC, Xanax and even ketamine on the backend.
It's the only way to deal with the abusive hours. We used to joke at a company I worked at-- that if you weren't an alcoholic, you would be in a couple of years.
Bad companies, really bad ones are setup like this: you have to break the rules to get your job done. But some people are blessed by management and others aren't. X breaks the rules because he's a brilliant leader, Y breaks the rules because he's a worthless loser. We had a VP and PM doing coke, fucking each other (very illegal in California), abusing the staff with bizarre and drug-fuelled behavior, all of which was ignored and encouraged. I was fired for "writing a rude e-mail." :-)
For a time, there was even a dealer in the buildings mail room. You put in an order, and in a couple of days, a DHL, FEDEX, etc. comes with your order.
There's a very real human cost to this stuff. I've seen guys have a stroke in the office due to pressure. If there's any way I can help, let me know.
