Smoking weed & Playing chess!

Okay So I've been smoking weed for the past couple of weeks on a regular basis and I've seen a decline in my chess 'game.' I started to lose more games and blunder quite easily. 

Does the same aove go for you too?
Let me know what you think? Can you play quality chess when your stoned or can it backfire and spoiil your game?

Cheers!
P.S. Here's a game I played when I was on a high!
