Final answer:
Candace exhibits substance intoxication, while Jason has a substance use disorder.
Step-by-step explanation:
The best level of involvement with alcohol that would apply to Candace and Jason is:
Candace: substance intoxication
Jason: substance use disorder
Candace became intoxicated at the office party and exhibited signs of alcohol intoxication such as slurring her speech and engaging in inappropriate behavior. Jason, on the other hand, has had his driver's license suspended multiple times for driving while intoxicated, indicating a pattern of substance use despite negative consequences, which aligns with a substance use disorder.
