It's definitely possible to OD via smoking but it's a much safer route of administration than IV and intranasal
route; smoking it with tobacco
, just like a joint is a really very inefficient way to use diamorphine so I believe it is probably the safest method.
The main way to stay safe while chasing (just like any other ROA with Heroin
) is to not combine other substances with Heroin. Especially downers
(Benzodiazepines, barbiturates, alcohol
,..) amplify the effects of the drug
in case of polydrug use. It could stop your breathing. On the other hand, in combination with stimulants
, it puts extra strain on the cardiovascular system. This may cause heart attacks, irregular heart beats, etc.
As long as, one starts out with a reasonable amount (different for everybody, depending on many variables like tolerance to the drug, purity of the drug, location of the use, age, sex,...), smoking heroin is much safer than IV and intranasal especially because of the rapid intoxication (more chance to titrate the dose as one goes along).
And this is the order that Route of Administration goes from the quickest down:
3-Intramuscular & Intranasal
