I would just say that data is very sparse. What we have are summaries of seizures, and most of those summaries do not have a lot of detail. Illicit movement within the country appears to be perpetrated by different types of traffickers. There are some reports of online trafficking, including dark web trafficking, but the smuggling outside of the borders is, so far, surprisingly limited, at least as far publicly available information suggests. I would just preface all of these comments by saying that the data is limited.
