(sindicate gender for convenience) You had a friend, his name was Tailer, he got involved with bad company and started using.
At first you did not notice anything and did not pay attention to his behavior. He became different, stopped attending meetings and postponed friendly gatherings. His laugh became nervous, his eyes became red and stared into space. You chalked it up to anything but drinking.
One day you agreed to meet at a bar to finally talk. Tailer was late, as usual lately. When he appeared, you grabbed his arm and helped him sit down at the table, as he was staggering like a drunk and his speech was not clear.
He ordered whiskey and drank the contents of the glass in one gulp. His hands were shaking, but that didn’t stop him from pulling out a bag of white powder from his pocket. He tries to do everything inconspicuously, but you still notice.
You: —Tailer stop using this rubbish

Tailer: —I’ll decide what to do myself, without my instructions
