It's difficult to rank drugs, but if you take a look at it based on different attributes the picture begins to become much more clear. In this chart, we ranked five of the most-used recreational drugs on popularity, cost, risk of harm, effects duration, and addictiveness. You can see for yourself where your favorite, or least favorite, drugs, rank out.
It should be noted that there are often steep drop-offs when it comes to mushrooms, MDMA, and cannabis. These three drugs are known for being some of the least addictive and least harmful drugs out there.
