I am looking for a sci-fi movie I remember from my youth. Given my age, I probably saw this movie in the 90es or early 2000s. I have no idea what the title was, but I remember this from the plot:
In the future, some company develops a drug that keeps you alive indefinitely, provided you take it regularly. If you stop taking the drug, you will die within a few days. To obtain the drug, the characters have to perform a job for the company, that involves playing some sort of computer game before an audience (some sort of e-sport?). I remember that the main protagonist was one of those players. For some reason, playing this game was an ethically questionable activity.
The plot evolves around the main characters trying to find the recipe for this drug, so it can be produced by someone other than its manufacturer.
There was also an older man who was some kind of "wise old man" character. At some point there was a big revelation that this old man was also addicted to the drug.
I also remember one scene were one of the delivery workers accidentally spilled some of the drug. The effect was that immediatelly some dead flowers on the wayside started to bloom and they had to kill the flowers with a flame-thrower.
That is about everything I can remember, I hope it triggers some memories. Of course I tried to google it, but without luck. I can't remember any names from the movie, so googling is difficult.
