Yes, you can, but you're tempting fate and breaking the law. You really do not want to be incarcerated in Laos.
Marijuana is most widely available in the cities, with opium in small country villages, where it is used legally as a pain reliever for very old people who have worked in the fields their whole lives. Other drugs are available, though none are legal. The Lao government requests that travellers do not engage in "drug tourism" for countless reasons, not least because it results in young Lao people getting addicted, and unable to contribute to a society that heavily depends on everyone's participation. And they don't have the same detox facilities if they become addicts as we do in the west, making it more likely they'll really stuff up their lives if they become regular users.
If you do try to tempt fate, be aware that although drugs are generally cheaper than in the west, quality and dosage vary tremendously. Methamphetamines are often passed off as ecstasy, speed and all types of other trash is passed off as cocaine, and so on. We have heard direct reports of sudden deaths of travellers after taking unidentified drugs.
