"i&#039;ve had back pain for 10 yrs from being an automobile mechanic. i had a fusion l3 tos1. i&#039;m also an addict. i&#039;ve been on and abused every pain med there is so my tolerance is very high. i&#039;ve found with butrans it keeps my pain away but no buzz so i don&#039;t abuse it.  it&#039;s not as effective as fentenyl but its decent."
