The grime star - real name Michael Ebenazer Kwadjo Omari Owuo Jr. - revealed that he had struggled with his mental health over the past few years and said smoking cannabis only exacerbated things.
In an interview with Carney's Community - a South London charity that helps disadvantaged young people - the 26-year-old said: "If you've got mental health problems, stop smoking weed. It's not good for your mental health.
"I have suffered with mental health problems for the past few years. When I used to feel depressed, I would lock myself away and smoke weed and I would just get worse and worse and worse. It does not help your situation. It will f**k you up.
"It feels good for, like, 20 minutes and then after that... we all know, us weed smokers, we know how it goes."
The Heavy Is The Head musician deleted his Twitter and Instagram accounts without warning back in February, shortly after sharing a post in which he flaunted a 'concierge card' issued by bakery chain Greggs. So yeah, strange way to bow out of the platforms.
But the rapper offered an indication as to why he may have got rid of the accounts in his interview with Carney's Community.
He said: "If you go on social media and it doesn't make you feel good, get off it."
Can't argue with that logic, to be fair. His Facebook account is still active though, so presumably that one wasn't making him feel bad.
Shortly before deleting his other accounts, Stormzy was involved in an escalating and fairly bizarre online feud with the 'Godfather of Grime', Wiley.
It came to a head on 15 February when Stormzy shared DMs that were allegedly from his former friend, claiming Wiley wanted the beef to be done with.
Stormzy tweeted: "'Wiley's a pr**k coz he love talk s*** then he sobers up and the begs it' is this you lot's Godfather?!?!
"You f***ing pathetic loser lmao @WileyUK about you hate yourself for this, is this your king?!? #iHateMyself #Loser #IamSorry #IwishThisDidntHappen #ThisManIs41."
The messages read: "You know what I just wanna this. I hate myself for this, just so you know.
"More than any battle I have ever had. Cos this did not mean more than our friendship and I threw it away. And I know this, I'm sorry."
In typical combative fashion, Wiley replied: "Don't post screen shots of me talking post you talking let's see what you was saying.
"I never repost what's said in the Dm but if I did all you man would look s**t so don't try that trick with me."
Thankfully, the deleting of Stormzy's Twitter account also signalled the end of the tedious to and fro.
