text: previous drug use? when i was a youth, i have experimented with several drugs. i  haven't done drugs in years and i'm interested in becoming a police officer.  i was told that if you have used drugs in the past, you cannont become a police officer.  is that correct? hey, i am a police officer and have been for the last 19 years.  past drug usage will not stop you from becoming a police officer.  as long as you disclose your usage when asked, you will be fine.  if you have any in your past, they will find out during the background check.  so, just be honest.  if you have any further questions, e-mail me and i will help if i can.    good luck.
