Mainly from the impoverished townships of Durban, even though it’s asserted to be emerging in different areas in South Africa too.

The material is frequently called a cocktail of various components, and these can differ, but the main active ingredient of the drug is heroin, commonly smoked with cannabis.

The drug may be said to comprise antiretroviral medicines especially efavirenz of this kind prescribed to treat HIV.  Evaluation of trials shows no such material, and authorities have commented that traders are proven to include”a variety of stuff” into medication to bulk it out.

Whoonga is utilized as a recreational drug; it creates intense feelings of euphoria, profound relaxation and endurance. Besides, it decreases appetite.

Outcomes of whoonga can last two to four hours. The drugs are generally smoked with cannabis in a joint, but a few processes of preparation for injection exist.

There are reports which claim whoonga addicts try to become HIV-positive because antiretrovirals are dispersed to HIV patients at no cost from the Department of Health. However, this claim is merely by speculation because some addicts are HIV positive and try to apply in practice as someone else to get double doses. Some addicts ask for medication at multiple clinics.
