People who are pro-legalization desperately want to believe that the marijuana is not a causal factor in all this, that it's just a trend that sick people like to smoke or at worst exacerbate their problems or cause "latent" illnesses to emerge. Exacerbation of such problems would be a very negative effect and so should anyways be taken into account when considering legalization.

If you want a scientific source, you could take a look at this recent paper :
