Like I know it's super fucked up to surreptitiously dose an unwitting mark, but wouldn't forcing a breakthrough experience on chuds help lead them out of darkness?
Here's a video of when the UK government did a field test of army members on LSD. They basically dropped their arms, stopped taking orders, and just wanted to play.
Like other people here pointed out, its a myth that LSD gets absorbed through the skin, your biggest chance is hitting their eyes probably, but with their helmets it wont work.
The only drugs coming to my mind that could work is either a fentalogue like carfentanyl or scopolamine, but fuck that, it kills them instead of pacifying.
