1.Jack noticed that his drug use doesn’t feel the same as it did the first time. He has increased his doses, and feels terrible when he hasn’t used in a while. He feels like he needs it. This means he has . Choose all that apply. developed a drug problem
developed a tolerance
become addicted
created a habit of taking the drug

Jack has developed three things 1. A drug problem 2. A habit of taking the drug and 3. He has become addicted to it

My evidence for this is jack has now started to take the drug on a normal basis making it a habit, he has also started feeling that without the drug he can’t function normally, and his doses have increased even more due to him becoming addicted to the drug.
