Stimulus properties of inhaled substances

Area of Science:

• Behavioral toxicology
• Environmental health
• Neuroscience

Background:

• Inhaled substances can influence behavior via toxic effects or by serving as discriminative stimuli.
• These inhaled compounds can trigger unconditioned reflexes and act as aversive or positive stimuli.

Purpose of the Study:

• To explore the multifaceted behavioral effects of inhaled substances.
• To highlight the significance of understanding inhalant stimulus properties for industrial hygiene and environmental quality.

Main Methods:

• Investigating inhalants as discriminative stimuli above olfactory thresholds.
• Utilizing respondent conditioning experiments (e.g., conditioned suppression).
• Examining inhalants in punishment and escape paradigms as aversive stimuli.
• Analyzing inhalants as positive reinforcers in self-administration studies (solvent abuse).

Main Results:

• Inhaled substances can function as discriminative stimuli, eliciting reflexes, and acting as positive or negative reinforcers.
• Chronic self-administration patterns (solvent abuse) demonstrate the positive reinforcing properties of inhalants.
• Laboratory techniques are available to study these behavioral properties.

Conclusions:

• The stimulus properties of inhaled substances significantly impact behavior.
• Consideration of these properties is essential for industrial hygiene and environmental quality decisions.
• Further research utilizing established laboratory techniques can elucidate these behavioral effects.
