While cocaine hydrochloride is often used in preparation for oral surgery, the Post Millennial pointed out that it is also abused for recreational purposes.

The website Addiction Resources explains, "Cocaine hydrochloride is a powder used in drug abuse or as a local anesthetic. Abusing cocaine hydrochloride can result in adverse side effects and risks.

One observer floats possibility that drugs may have been left by Hunter Biden

"Cocaine can be processed to produce three different forms of the drug: cocaine hydrochloride, freebase cocaine, and crack cocaine," it goes on to add.

This led PJ Media writer Matt Margolis to suggest that Hunter Biden may be involved in the incident, stressing how he "was recently at the White House for a state dinner."

Biden has had a long and well publicized history of drug abuse, a fact which was documented in videos and pictures found on his abandoned laptop.

What's more, the president's son recently entered into a plea deal for illegally purchasing a firearm while addicted to crack.
