ELI5: If a mosquito bites me while I'm under influence of a drug, does it experience the same effects as me?

Your question is pretty complicated. The first issue is whether or not drugs that affect humans would have an affect on an insect, and the second issue is whether blood contains remnants of those drugs.

Alcohol, for example, does have an affect on insects. It can disorient fruit flies or even cause bee's to fly upside down. And, when you drink, alcohol does actually get in your blood stream while it is processed... however, it is so diluted that for it to have an affect on a mosquito, you'd likely need to drink to the point of death before it'd have an affect on a mosquito.

Other drugs get more complicated. Drug tests, for example, don't really find "drugs" in your system, they often find the "metabolites" of drugs (the remnants that are left over when a person has taken drugs). For example, if someone ingested a lot of Marijuana, it could show up very clearly in their blood for weeks... but what shows up is not anything that would cause the affects of marijuana. Rather, it is the left-overs chemicals from your body processing the marijuana.

So the answer to your question really depends on the specific drug in question -- however, given the other issues, it is unlikely that a drug would leave any residual active components in your blood which could then have an affect on an insect that drinks your blood.
