The crimes listed at that link are making, selling, importing and exporting drugs.
How are these 'opportunistic'? All of them require planning.

Perhaps I do, and perhaps I don't. But I'd prefer we discuss the issue than my general view of the world.
Let's take your scenario: someone is on the brink of starvation, and an opportunity to sell drugs (and not starve) falls in their lap. They take it (without any prior plan). This is definitely opportunistic.
What happens if the above situation is repeated a second time? Do we consider that opportunistic as well?
How many times does someone have to take such an opportunity before we consider them selling drugs as being 'what they do' or part of their plan?
Unless the chance of being arrested is close to 100%, it's unlikely that someone's first arrest for selling drugs coincides with the first time they sold drugs. So is it really opportunistic?
There might not be other opportunities available. Until we've eliminated the threat of homelessness and starvation for everyone living here (which we absolutely could do), there will always be people who had no other choice.

Some data that suggests many get into it to feed their own addictions (which can be a "no other choice" scenario), meant more are collected by police as "dealers" even though they are just holding drugs for personal use. There's lots of research here, unsurprisingly.
