This does not matter. In a criminal context weapon usually means something capable of inflicting great harm as a tool commit or execure a crime. If you steal something while having a screwdriver in your backpack you are screwed (literally) since you could have used it for executing the robbery. While the rules here may not be that strict (possession of said drugs while commuting sexual assault) using drugs to commit sexual assault of any form would be the same as using a knife to force the victim to not resist. There are no further classifications like chemical or mechanical weapon, since it does not matter.







Drugging someone is maybe not manslaughter (depends on what drug you use and what dose you use) but it is always assault and can be prosecuted as such.
