Far as hard drugs are though that's the past
Eminem is talking about his past drug abuse, emphasizing it being in the past. Eminem used to do drugs so hard he was two hours from death following an overdose at one point. Of course, that’s all behind him, and he’s been very open with his Recovery.
Em also struggled with alcohol abuse; the two are often related. He even frequently wears the Alcoholics Anonymous symbol as a necklace pendant (e.g. during the 2011 Grammys), a further message that the addictions are in his past.
