Which strategies can a person practice to prevent the use of harmful substances? - avoid activities with others - confide in a proven trusted adult - use social media to get peer advice - seek friendships only with older people

- confide in a proven trusted adult

Explanation:

"Confide in a proven trusted adult" is the only option that shows a strategy you can adopt to prevent the use of harmful substances. A trusted adult will be able to correctly advise you to look for alternatives that do not harm your health and well-being so that you do not need to use harmful substances. Getting peer advice, however, is not a good choice if you are too young to be able to filter out good advice from bad advice.

Making friends with seniors is always good, but making friends with seniors is not ideal, you also need friendships with people your age who understand what you are going through and who like the same things as you. And that includes you hanging out with different people, always being careful to move away from friendships that aren't good for you.
