>chasing the dragon is a euphemism for taking heroin

Now let's talk about Charlie Weasley.

>Skilled enough to have become professional at quidditch

>Bonds with Hagrid because they both love "dragons"

>Begins struggling in school despite being known as a decent student, fails his apparition test.

>Graduates from Hogwarts the year before Harry & the gang start

>Immediately leaves the country because he likes dragons so much, moves to Romania to "study"

>Apparently it's a very, very short education, because by November, he's a professional at the "dragon sanctuary"

>Weird, since it's apparently such a dangerous occupation that "dragons" have been outlawed.

>Learns that Hagrid has a "dragon"

>Arranges a deal at the astronomy tower

>Sends two friends to pick up the "dragon" and bring it back to the "dragon sanctuary"

Quote from Charlie's letter regarding getting the "dragon" to the "sanctuary":

"I think the best thing will be to send him over with some friends of mine who are coming over to visit me next week. Trouble is, they mustn't be seen carrying an illegal dragon."

Why not? I thought they were professionals. This is starting to look like shady business. If anybody sees two professionals handling a dragon, will they really question them, considering that it's the same guys who are trusted to carry dragons into Hogwarts for the Triwizard Tournament 3 years later? Could they not think of a single, legitimate reason for two dragon handlers to handle a dragon, that they could use to lie themselves out of the situation?

Now let's look at the rest of Charlie's life:

>Is "too interested in dragons", never marries or has kids

>As of 2014, this is still true, according to Pottermore.

>His face is weather beaten from "working outdoors", he often has minor injuries, especially on the hands and arms, callouses on his fingers

>Hated that his mother used to cut his hair short

Conclusion: Charlie Weasley, who grew up in the 70's and was young in the 80's and 90's, not to mention well-informed about the muggleworld, was rock n roll as fuck. He idolized rock and metal stars and took a liking to the H. When his addiction got out of hand, he left his home country behind and joined a metal band instead. He plays fingerstyle bass, which explains the callouses on both hands. He also likes real dragons, and has actual friends who are dragon handlers, as seen in book 4, which is also why he decides to name the mansion that he buys for the money he earns touring "Dragon Sanctuary".

Charlie Weasley still has a severe heroin problem today, and can't maintain a relationship. He instead gets his love from random flings with groupies.

Statistically, based on the life expectancy of heavy heroin abusers, Charlie will be dead within 10 years, maximum.
