overall , if you are intoxicated in any way at anytime because you choose to try alcohol or drugs then at anytime in the future any lawyer can ask you if youve ever drank alcohol or done drugs and if they can prove that you have then they can destroy your credibility which means they can give the judge and jury enough justification to make people believe your word is not reliable because when you cant think clearly then you cant identify a person accurately or the truth about a situation or event accurately because you chose of your own free will to have your mental capacities impaired so therefore you are not a trustworthy person for any testimony or as a witness in court .
