What strategies can a person practice to prevent the use of harmful substances? be a positive role model. confide in a proven trusted adult. use social media to get peer advice. choose friends who do not use drugs. build your relationship with your parents.

The strategies you can use out of those opinions that would be best are, confide in a trusty adult , they can be a mentor and give you help. How can you be a role model when your dealing with drug issues. Help yourself before you try to help others , so when you go to show examples they are genuine and pure. Social media can be a trap I would personally stay away from that option. Choosing friends who don’t use drugs is a really good one. Surround yourself with people who are healthy. Last but not least every parent is different and that depends on your current relationship and if you think they are able to help you , do you trust them. That will be your judgment call.

Ithink the answer is c.  hope this is right and
