Possible to live a NORMAL life with weed?

I wonder if in about 20 years it will catch up with me? I'm going to school for dental hygeine so it's not like it's a really BIG deal or anything but anyone else experience this?

Nancy,this is just one person's testimony.
When I was in high school I didn't use cannabis.I failed terribly in HS getting grades like d's and f's consistantly.I got so bored and dis-enchanted with school I dropped out and joined the marines.
It was after leaving the marines I first tried cannabis.That was 33 years ago and i've used ever since.I led what one could call a fairly normal or ordinary life.I met a woman fell in love married had children and worked to support them and myself with no problems.
Today I run my own buisness and have a BA degree.I've thought about a masters but I haven't been able to justify it to myself so it is still on my back burner of things to do.
Cannabis has not hindered me in my life.It has relieved my stress though many times.It has put a smile on my face when nothing else could or would.
I found that in my experience with cannabis it's effects grew and matured with me over the years.At one time it was just a way to unwind and have some fun.Then I learned it could enlighten me as I traveled thru personal passage after personal passage.It inspired my creativity.It inspired my thirst for knowledge.In my older age it has relieved many of the pains of rheumatoid arthritis and degenerative disc disease.
I could go on and on but i'll close this for now and hope that you too will get passed the stygma the governments of the world have placed upon those using thekind herb and the herb itself.Hence,it is what I believe that drives your fear of prolonged use.It is not the plant that causes the pain but an un-informed society full of self-righteousness and false nobility led by politicians who feel they have a right to tell people what is good for them to put into their own bodies and what is not,as if it were their choice and not the individuals.
The use of cannabis is an unalienable right that can neither be given by any man or taken by any man.
Want to know what WILL catch up with you in 20 years? Alcohol and tobacco if you are unfortunate enough to use either and continue using it for all that time.But of course that is legal and acceptable in our society.
