We can't tell exactly without the atoms labeled.
It seems to not show double bonds either, if that is a carbon chain, then most of those carbons have a positive formal charge.
Last bit looks like it's an amine group with two methyl groups substituted for the hydrogens.
Since there is no double bonds shown, I'm guessing that is a benzene ring.
EDIT: Just came to my head. Isn't this a bad representation of dimethyltryptamine?
EDIT #2: Nope, it's similar. Sees to be 3-(1H-indol-3-yl)-N,N-dimethylpropan-1-amine.
