Here's some cons:
Adopted people are over represented in the mental health and prison services. Are at least 4 x more likely to try to commit suicide (more recent studies say it's more).

Many people who have been adopted struggle to make sense of their identity and place in their adoptive families. They may feel disconnected from their cultural heritage and experiences that could have been part of their life had they not been adopted. People who have been adopted may also grapple with guilt or abandonment when forming relationships with friends, family members, partners, or future children who will never know their birth parents or vice versa.
The Long-Term Impact on Identity
People who have been adopted often struggle with a complex sense of identity due to their loss. This can manifest in different ways depending on the individual, but it usually includes feelings of confusion, shame, or inadequacy. Remember, these feelings are normal and valid; they don't make an adoptee any less valuable or loved by those around them. Having a solid support system—including other adoptees—can help an individual better process their identity as someone who has been adopted over time.
Influence on Relationships
The loss experienced by people who have been adopted can also harm their relationships with others. This can often lead to feeling disconnected from one's family or friends. It may also cause an individual to feel like they have difficulty connecting with people emotionally or trusting them. Conversations about these feelings can help individuals build stronger connections with those around them and find solace in meaningful relationships with family members and friends.
Mental Health Repercussions
The feeling of loss has been linked to numerous mental health issues, including depression, anxiety, post-traumatic stress disorder (PTSD), substance abuse, and more. For many adoptees, understanding the root cause of these issues is critical to addressing them healthily and seeking necessary help. Some resources available include therapy, support groups specifically for adoptees and their families, online forums/blogs/websites dedicated to adoption topics, workshops aimed at helping individuals cope with the pain associated with adoption losses, and more.

A decades-long nationwide Danish study followed over 13,000 adoptees.
They found that adoptees were 30% more likely to die before age 65 compared to non-adoptees.
This wasn’t just from one cause. It spanned across:
Cancer
Infections
Vascular disease
Alcohol-related deaths
Suicide
Even beyond age 65, adoptees continued to show significantly higher mortality from all-cause, cancer, alcohol-related deaths, and suicide.
It really depends on who's positivity you're looking for. Adoption is a traumatic life long event for the adopted person. Issues may present as younger children or as they grow older.
