Answer:
more than 80 percent
Step-by-step explanation:
Heroin is a type of opioid drug which is made from a natural substance called the morphine taken from the opium poppy plants. It can be in the form of white powder or black sticky tar. It is an highly addictive drug and is illegal to consume sell or produce this drug.
In the context, a man who is a drug addicted has consumed ten bags of the drug heroin for the last 16 years. There is only a sober period of three months in jail. And now he wants to refuse the addiction treatment. Though he plans to self taper off heroin, his chance of relapsing is more than 80 percent over the next twelve months.
