Best horror movies to watch high?

My recommendation is don't do drugs.

I used to cane the weed in my teens and one of my favourites to watch was Friday Part 6: Jason Lives, it has all the stoner elements one could ever want; a killer soundtrack, comedy deaths and a smokin hot final girl.

I also remember watching From Beyond with some mates while we were getting totally baked, when I say watching it, what I mean was it was on in the background lol but that's a fun and trippy film to watch while smoking!

But the best one of all (in my experience anyway) was Jackson's 'Bad Taste', I first watched that with about ten of my little tearaway mates when I was about 13, we had an ounce of skunk, a bong and a VCR player, Bad Taste on video provided us with one of the funniest sessions and an evening I'll always remember fondly to this day.

One Eye monster

Dead Alive

Or Eraserhead!

The only way to watch this movie is stoned--or, as one reviewer said

Dude....The best horror movies to watch high are ALL OF THEM

Use your brain, kid!

Mightboosh is great stoner material...it will take you on a journey you will only understand when your high.

Well you never said what type of hi you and your buddy are gonna be on and that makes a big difference...
But I take it as a few beers and get out the bong!

or if ya gonna trip on shrooms its a whole different game! hahaha

But for a basic high:
A Serbian Film
Flesh For Frankenstein

thats all I/m giving at the moment so

I've never watched a movie while high, but I've seen quite a few while drunk.  Our group usually loves to throw on a Nightmare on Elm Street or Friday the 13th movie when we do some heavy drinking.

For one, there's plenty of stuff to quote, they tend to have the right amount of horror/comedy,   and when you're really drunk you can find plenty of hidden subtext in those movies.
