The survey is based on DSM-5 criteria, hence it includes under the "Hallucinogen" group several substances which are not classic serotonergic psychedelics, and excludes MDMA which is categorized under "Club drugs".
Substances included in the study are:
Lysergic Acid Diethylamide (LSD), peyote, mescaline, psilocybin, anticholinergics, N,N-Dimethyltryptamine (DMT), 2,5-Dimethoxy-4-methylamphetamine (DOM), Dimethoxybromoamphetamine (DOB), Salvia divinorum, dextromethorphan, and phencyclidine.
Based on previous epidemiological studies, a significant majority of "hallucinogen" users (as defined above) are in fact users of classic serotonergic psychedelics (such as LSD, psilocybin, mescaline and DMT).

None that I know of, but I am not as updated on research of alcohol use disorders as I am with cannabis.
One interesting frontier is using machine learning methods for causal inference (the reason I have some vague knowledge of this is that my brother is working on this...). These may hopefully allow for some interesting analyses of existing data.
Here is a link for his seminar on causal inference for observational studies: http://www.cs.nyu.edu/~shalit/slides.pdf

I personally am in favor of decriminalizing cannabis use, as well as other drugs. Unfortunately, the debate regarding legalization is very polarized, and tends to not be based on scientific findings. One side tends to demonize cannabis while the other dismisses any information regarding negative effects. I believe there are many reasons for legalization, but mainly as a method for harm reduction, not because cannabis is some sort of a wonder-drug. Here are some studies regarding long-term negative effects:

Our findings in no way imply cannabis use causes suicidality. There are many other factors we couldn't analyze which could be the cause of this association. The reality is that these two behaviors (cannabis use and suicidality) are very complex, and this study is just one small step in the understanding of how these complex behaviors interact.
I believe proponents of cannabis legalization should look at all the data regarding long-term effects of cannabis with as little bias as possible - there are enough good reasons for legalization, it is dangerous to ignore scientific data regarding risks.

The publisher gives a link for sharing on social networks which works for 50 days, after that, it's paywalled.

Regarding legalization- we had no relevant data, so I can't say. The bidirectional association may indeed indicate a third cause, as discussed in the paper. I have added a link that should allow access to the full-text, let me know if it doesn't work for you.

Illegality is indeed one of the possible mediators of the association. A recent study has demonstrated decreased suicidality in states where cannabis was legalized
