Can you smoke marijuana after taking nasal decongestant?

On the real, I don't know if anybody else has these effects, but I smoke weed about 7 to 8 times a day and when the one time I took mucinex with it I tripped straight balls. It was a weird trip that i dunno if i could describe this far after it but if you wanna get f***ed up there you go

I just did it and it seems ok. Its noticeably harder to type though.
