Formula 1 drivers complained this week about the smell of marijuana as they prepared for the Las Vegas Grand Prix, with one even joking they could fail drug tests. Marijuana is legal in Nevada and the odor can often be prevalent among those attending sporting events.

With their driver at risk of missing this weekend's Las Vegas Grand Prix, a Formula 1 team have released a key health update.

While experts predict this year’s race will pull in slightly less than the $500 million or so in revenue for Formula 1 and the $1.5 billion in Las Vegas economic impact achieved in last year’s race, the contest and its weeklong festivities will still be a boon for all those involved.
