The dose for LSD to be harmful is extremely high and you would likely never encounter anyone selling anywhere close to the amount needed. The biggest threat to the user is the contamination of the LSD by possibly fentanyl or other opiates due to the unregulated nature of the black market.

Really I think we should go a step beyond this. Being able to go to some new planet is not guaranteed or that planet may even be inhospitable to us.

What I think is more feasible and more benevolent than preventing a mass extinction is we should slowly expand our orbit so we can survive the brightening sun for at least a while longer. Basically, all we need to do is increase our planets speed over hundreds of millions of years. A certain mass of asteroids with steerable self correcting orbits could push small amounts of speed into our planet that would build up over time.

Even if we don't make it, we at least give life more time to do it's thing.
