Can long time marijuana use lead to permanent nervous system damage?

I smoked marijuana for two and a half years just
about every day. I stopped for a couple of months, then smoked again, and I had
my first very intense anxiety attack. After this happened, my anxiety
continuously increased getting worse and worse. I noticed throughout my anxiety
attacks, and especially in the first one I had, that my vision was REALLY
disoriented and it felt like everything was spinning or flipping over. My heart
rate was very fast too.

I went to the doctor for my anxiety and they did an ANSAR test on me. They said
my sympathetic and parasympathetic nervous system(s) were imbalanced and
abnormally high. I was prescribed to Alprazolam for my anxiety but it is no
longer working for me.

I get extreme anxiety when I'm not high on marijuana now too. I've stopped
smoking because it gives me a horrible anxiety attack and I think sometimes I
even hyperventilate.

I have heard studies about marijuana causing anxiety and depression, so I would
like some insight. Thanks.
Absolutely, it can cause nervous system problems. But, it doesn't take long at
all. Depression usually appears in marijuana users because their tolerance for
it has built up so much that it no longer makes them 'happy'. Instead, it does
the exact opposite. It does this when the user isn't using as well.
prolonged use can mess you up period. you are seeing parts of it and parnoid
behavior is one thing that is bad about this drug also. you see no one shoudl be
taking this drug its a drug and it can mess your body up big time plus side
affects its not safe like all think it is. take careand good luck
I smoked it for just 6 months at one time and it really screwed me up too. I
sometimes have flashbacks, even 10 years later. It also messed up my metabolism
and memory. The depression actually got better.
it can give you life long paranoia
yes.
yes, weed is a medicine, its not good to take when u dont need it, just like
other medicines, if u take to much bad things can happen, and your weed may have
been laced with something stronger like speen or extacy... prolly was most weed
is. unless u kno it was home grown. otherwise it was laced. only take it when u
need it! weed is a cancer treatement and pain killer, just take it wehn u need
it only. and eat it cuz eating it doesnt do as much damage, it will still work,
it just will take longer to work. peace, take care of uself. exersize. eat
healthy.
I grew up with parents that smoked. I dont view it as bad because it never
stopped my parents from being great parents and providing a good live. I saw
them get up and go to work everyday, we had our home and they had 2 rental
properties in my eyes life was great.

My mother passed away in 2006 but my father is still here, and he still smokes
his pot and I dont know of any nervous system damage. I'm sure he has never been
tested for it either, and I have been around him plenty when he was on it and he
is definately not anxious or nervous.

Anyway, I would assume it affects people differently, but standing on the
outside looking in, I am 99.9% sure it has not affected my parents the way it
has affected you, and they were/are longtime users.
