If the want of perception or will is due to drugs, or narcotic or intoxicating substances taken voluntarily and knowingly by the perpetrator, he shall be punished for the crime committed, as if it were committed free of narcotization, or intoxication, even if such crime requires a particular criminal intention. If the perpetrator has intentionally taken the drugs or intoxicating or narcotic substances for the purpose of committing the crime, this shall be deemed as an aggravating circumstance with regard to the penalty.
