Salt (NaCl) is far more soluble in water than THC. NaCl = 357 g/L, THC = 2.8 g/L.
Now, THC is less soluble in 0.15 M salt water (0.77 g/L) than in pure water (2.8 g/L) because of ionic strength effects. As THC has no ionizable functional groups, solubility in water can only occur through hydrogen bonding effects. Therefore, Increasing the concentration of NaCl in solution effectively reduces the concentration of water molecules available for the THC to hydrogen bond with, so its solubility decreases.

look at the structure. there's a bunch of sites with potential H-bonding. that's where the solubility comes from

Just adding to the previous answers...
If I am not mistaken, increasing the ionic strength, increases the dielectric constant of the medium and thus the H-bonds are also weaker.
