Tish Cyrus is looking back at her parenting and seeing ways she could’ve improved … chief among them, rolling up a joint and mellowing out a bit!

The mother of Miley and Noah Cyrus opened up about her parenting skills on a recent episode of her “Sorry We’re Stoned” podcast … telling guest Wiz Khalifa she regrets not doing some toking back when her kids were growing up.

The way Tish puts it … she didn’t pick up the Mary Jane until she was in her mid-40s, years after her kids were in their teens — so she feels she wasn’t as much fun as she could’ve been with a little pot.

Tish’s daughter Brandi — seated right alongside her mom — said she probably woulda chilled out about a few things too … a jab Tish couldn’t have agreed with more.

BTW … Wiz also has a song about smoking weed with Miley Cyrus titled “23” which came out in 2013 — a song that made a then-anti-marijuana Tish really upset!

It’s a bit ironic Tish is looking back on her parenting … since a lot of people online are currently gossiping about her relationship with her daughter Noah.

Remember … reports surfaced earlier this week that Noah was actually dating Tish’s new husband Dominic Purcell first — before Mama Tish swooped in and stole him away.

The Cyrus family’s dealing with a ton of issues … with Miley not thanking Billy Ray Cyrus in her Grammys acceptance speech and Noah reportedly estranged from TIsh.the
