The use of illegal drugs, including clubbing drugs such as ecstasy, is quite prevalent in Vegas. Dealers will approach you all over town, but take care. And always watch your drinks: illicit drugs are sometimes slipped into unattended glasses.
The local authorities have a strict zero-tolerance policy on drug use and trafficking. If you're implicated in a drug sale or purchase, you will be arrested and charged, and if convicted could receive a maximum sentence of five to ten years in jail.
Tipping is a way of life in Las Vegas. Limo drivers ($10–$25 per ride), valet parking attendants ($2–$5), cocktail waitresses ($1–$2), housekeepers ($2–$4 a night) and even desk clerks ($10–$20 if you’re looking for a better room) all ride the tip gravy train.
This also goes for casino dealers, who are paid little more than the minimum wage. Giving tips (or "tokes", short for "tokens") is smart, as happy dealers are your friends—they can assist you in a number of ways, such as by slowing the pace of the game in your favor. It's best to toke after a big win, for example by placing a bet for the dealer alongside your next wager. But don't bother if the dealer is rude or uncooperative—in such cases, it's best just to move to another table altogether.
In 2007, smoking was banned in most establishments that serve prepared food (casinos and strip clubs were exempt). However, many businesses flouted the law, and it remains a matter for debate whether continued enforcement is possible. Smoking is ubiquitous on casino floors, though a couple have non-smoking areas. A few hotels (such as the Four Seasons) are entirely smoke-free; most others offer non-smoking rooms.
