No, you're the one bombing thousands of innocent civilians on TV.

Abstract:Heavy marijuana use has well established long term
consequences for cognition and mental health, but the effect on brain
structure is less well understood. We used an MRI technique that is
sensitive to the structural integrity of brain tissue combined with a
white matter mapping tractography technique to investigate structural
changes in the corpus callosum (CC). Diffusion tensor imaging (DTI)
was obtained in eleven heavy marijuana users who started using
marijuana in early adolescence and eleven age matched controls. Mean
diffusivity (MD) and fractional anisotropy (FA) (which measure
structural integrity and tract coherence, respectively) were analysed
within the corpus callosum which was spatially defined using
tractography and tract-based spatial statistics (TBSS). MD was
significantly increased in marijuana users relative to controls in the
region of the CC where white matter passes between the prefrontal
lobes. This observation suggests impaired structural integrity
affecting the fibre tracts of the CC and is in keeping with previous
reports of altered and diversified activation patterns in marijuana
users. There was a trend towards a positive correlation between MD and
length of use suggesting the possibility of a cumulative effect of
marijuana over time and that a younger age at onset of use may
predispose individuals to structural white matter damage. Structural
abnormalities revealed in the CC may underlie cognitive and
behavioural consequences of long term heavy marijuana use.
