This is the most reductionist poll I've ever seen on here.
How so?
Because there is a wide array of possible policy preferences on abortion, and I guess on cannabis too.
Yes, there is a list of policy preferences.
Concerning abortion, there are two extremes: at one extreme, there are the ones who think that even contraceptives are against life, at the other extreme, there are the ones who think that even a 8 month fetus could be aborted. In the middle, there are the ones who think the pill after sex is acceptable but the abortion not, and the ones who think that abortion is acceptable until 3 months. There are also divergences concerning the situations: there are the ones who think that abortion should always be illegal, there are the ones who think that abortion should be legal in cases of rape, pregnancy risky to the woman's life and acephalia, there are the ones who think that abortion is a issue of choice. But to keep things simple, it is possible to say that people who think abortion is a choice issue and that should be legal until 3 months can be considered someone who supports legal abortion.
Concerning cannabis, there are also different policy preferences. Some countries forbid cannabis even for medicinal uses. Some countries alllow cannabis for medicinal uses. In Portugal, it is legal to hold small quantities of cannabis, but not to sell. In Netherlands, it is possible to buy and consum cannabis in the coffee shops. In Uruguay, each person can buy a limited quantity of cannabis in the drugstores. Although even in Netherlands and Uruguay the cannabis is 100% legal, it is possible to say that people who support these models are pro-legalization.
