I have been on the maximum dose of Abilify pills (30mg) for over a dozen years and never had trouble getting high from cannabis while on the medication. I quit smoking daily a year and a half ago due to my living situation so only smoking once every 2 weeks or so has caused my tolerance to drop a lot. Now I have to smoke waaaaayy less than I once did to get a buzz unless I want to induce a panic attack.
And I will echo what
@Darksidesam said in that cannabis has been known to increase the likelihood of psychotic episodes in those at risk of having them. So if you do believe Abilfy caused this and are tapered off, please practice smoking in moderation until you can safely gauge your tolerance.
Like
@Snafu in the Void stated, I don't think an AP like Abilify can permanently block a drug, especially not cannabis.
Do you mind if I ask what you have been smoking? The reason I bring this up is sometimes people start smoking concentrates like wax/dab and their tolerance goes up so high that flower stops working until they quit the concentrates.
