i just looked up information about heroin overdose and it lists symptoms including low blood pressure and weak pulse. Do you know how a heroin overdose may cause them?

Heroin is a depressant. Hence it depresses cardiac output. Reduced cardiac output causes the low BP and the weak pulse.

Heroin, or diacetylmorphine (INN), also known as diamorphine (BAN), is a semi-synthetic opioid drug synthesized from morphine, a derivative of the opium poppy. It is the 3,6-diacetyl ester of morphine (di (two)-acetyl-morphine). The white crystalline form is commonly the hydrochloride salt diacetylmorphine hydrochloride, though often adulterated thus dulling the sheen and consistency from that to a matte white powder, which however heroin freebase typically is.[1]

As with other opioids, heroin is used as both a pain-killer and a recreational drug and has an extremely high potential for abuse. Frequent and regular administration is associated with tolerance, moderate physical dependence, and severe psychological dependence which develops into addiction.

Internationally, heroin is controlled under Schedules I and IV of the Single Convention on Narcotic Drugs.[2] It is illegal to manufacture, possess, or sell diacetylmorphine without a licence in Belgium, Denmark, Germany, Iran, India, the Netherlands, the United States, Australia, Canada, Ireland, Pakistan, the United Kingdom and Swaziland.

Under the name diamorphine, it is a legally prescribed controlled drug in the United Kingdom. It is available for prescription to long-term users in the Netherlands, the United Kingdom, Switzerland, Germany and Denmark with counseling to deter addiction.[3][4]
