decent cannabis alternative?

[untoasty1]

Basically, i'm looking for something that sedates you, and gives you higher music appreciation (this is key), and still lets you function to a certain degree, but isn't particularly addictive or bad for you. I need an alternative because i am now getting drug tested on a monthly basis and weed stays in your system too long. any suggestions?

for reference, i've already tried:

amphetamine
temazepam
hydrocodone
dxm
gabapentin

but to no avail.
