The guidelines from the IB are very explicit in terms of ethical guidelines.

Therefore your work for any assessment task must not:

• Damage the environment
• Glamorize the taking of drugs
• Inappropriately reference socially taboo subjects
• Incite or condone intolerance or hatred of others
• Include excessive or gratuitous violence
• Make reference to, or represent, explicit sexual activity
• Avoid situational advertising & branding
