Quick tip, don't use the word opioids over and over again. It gets annoying to read.
Use pronouns such as them or it.
For example:
Sometimes people use opioids to help with an injury but, sometimes people will use them just to get high.
Something else
Can you tell who is and who is not using opioids legally or illegally? You can’t tell who is or is not using the opioids that they have legally or illegally.
Take out 'the'.
And instead of 'Can you tell who is and who is not using opioids legally or illegally?' say either 'Can you tell who is using opioids legally or illegally?' or 'Can you tell who is and who is not using opioids legally?'
Also paragraph 3, you switch pronouns from he to them. Grammatically, this doesn't make sense.
I hope this helps!
