Alright, I have had this one in my mind for years. Only have bits and pieces left that I can remember. I saw it once when I was a kid. Late 80's, possibly early 90's sci-fi/horror. Basically, there is a slimy alien parasite who latches on the the back of some guys neck and shoves a long, mosquito-like appendage into his brain and squirts some kind of psychedelic juice into his brain that makes have some weird acid trip and also makes him kill people (perhaps for some bodily fluid extraction from the victim?)
Anyway, all I remember is the kid gets addicted to the alien brain juice and always wants more. They may have spoken through telepathy. A scene with a junk yard where the cars turn all kinds of crazy colors after he gets juiced. Possibly another scene where he kills a girl who is about to give him some lovin' and later finds blood on his underwear. And lastly, when he tries to get rid of the alien it squirts a crap load of the brain juice into his head and he has a major freakout!
If anyone can help, please do. I have to know what this movie is!
That would be "Brain Damage"

The Synapse R1 DVD of this is pretty darn good in terms of quality. From what I have seen, Synapse does a good job with all of the movies they release on DVD.
